Add unwind symbols to the kernel too... not sure it goes here though.

Stubbed out config_manager and pci bus_manager arch code.
Now really use the boot floppy tgz for the netbsd uimage as it all builds, but with other kernel arch code not yet commited.

Move the unwind data out of the bss section, it broke bss init which ended up erasing real data and making dprintf do weird things...

- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
	- add various addresses, boot script, custom C/C++ flags and SD card definition,
	- not sure BoardSetup is included at the best place though,
	- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.

50d22f83ef The reference of the currently active translation map shouldn't be released
until the data it protects isn't in active use anymore. Previously it would
release the translation map and therefore the page directory reference while
the page dir was still set on the CPU, as only the actual call to
i386_context_switch() will replace the page directory in the control register.
This didn't cause any harm though, as during the context switch interrupts are
disabled and therefore the page directory would only be deferred_delete()ed and
not directly freed/overwritten. Still this is logically more correct.

86766d6aca * handle_driver_events() kept the sDriversListLock locked over the whole
time. But since this is also locked from within the driver/directory watcher
  (with the node monitor lock held), and handle_driver_events() could cause
  node monitoring updates, the locking order could be reverted, causing a
  deadlock (I just ran into).

ee280b59e9 Prevent the user TLB invalidation function from being preempted by turning off
interrupts when invoking it. The user TLB invalidation function essentially only
reads and writes back control register 3 (cr3) which holds the physical address
of the current page directory. Still a preemption between the read and the write
can cause problems when the last thread of a team dies and therefore the team
is deleted. The context switch on preemption would decrement the refcount of the
object that holds the page directory. Then the team address space is deleted
causing the context switch returning to that thread to not re-acquire a
reference to the object. At that point the page directory as set in cr3 is the
one of the previously run thread (which is fine, as all share the kernel space
mappings we need). Now when the preempted thread continues though, it would
overwrite cr3 with the physical page directory address from before the context
switch still stored in eax, therefore setting the page directory to the one of
the dying thread that now doesn't have the corresponding reference. Further
progressing the thread would release the last reference causing the deletion
of the object and freeing of the, now active again, page directory. The memory
getting overwritten (by deadbeef) now completely corrupts the page directory
causing basically any memory access to fault, in the end resulting in a
triplefault. This should fix bug #3399.

56c6c0fefb - introduced an "argumetns" field in stage2_args to hold command line args from chaining loader,
- added some multiboot support code:
	- dump some of the passed info,
	- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

255c9104e5 * Rework the heap locking strategy. Use a read-write lock for the area lock to
allow for more parallelism. Also introduce seperate locks for the bins and
  for page allocation. This greatly reduces lock contention and reduces the
  duration the locks are held due to them overall protecting less code. Now only
  allocations of the same size hitting the same allocator or allocating larger
  chunks of memory should block. Previously, basically any allocation and also
  free would be mutually exclusive, making it scale pretty badely.
* Added memalign_nogrow(). As it uses heap_memalign() anyway, there's no real
  reason not to allow for an alignment.
* Some cleanup.

ea2abd110b * Renamed the ROUNDOWN macro to ROUNDDOWN. Also changed the implementation of
ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
  two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
  when other functions were invoked. Trying to trick the compiler wasn't a
  particularly good idea anyway, since the next compiler version could break
  the trick again. So the general policy is to use the fault handlers only in
  assembly code where we have full control. Changed that for x86 (save for the
  vm86 mode, which has a similar mechanism), but not for the other
  architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
  fields in the cpu_ent structure, which must be used instead of
  thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
  not be used in the kernel debugger either. Introduced a debug_memcpy()
  instead.
* Introduced debug_call_with_fault_handler() function which calls a function
  in a setjmp() and fault handler context. The architecture specific backend
  arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
  debugger. It determines whether a range of memory can be accessed in the
  way specified. The architecture specific back end
  arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
  for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
  the current thread pointer in the kernel debugger. When entering the kernel
  debugger we do some basic sanity checks of the currently set thread structure
  and unset it, if they fail. This allows certain commands (most importantly
  the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
  page faults. This allows us to gracefully catch faulting commands, even if
  e.g. the thread structure is toast.

We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.

a9c45a68ef Add MultiBoot support.
Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko.
- used defines for clarity, the rest of teh code could make use of them too...
- added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID,
- conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly,
- added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled.

671a2442d9 More work towards making our double fault handler less triple fault prone:
* SMP:
  - Added smp_send_broadcast_ici_interrupts_disabled(), which is basically
    equivalent to smp_send_broadcast_ici(), but is only called with interrupts
    disabled and gets the CPU index, so it doesn't have to use
    smp_get_current_cpu() (which dereferences the current thread).
  - Added cpu index parameter to smp_intercpu_int_handler().
* x86:
  - arch_int.c -> arch_int.cpp
  - Set up an IDT per CPU. We were using a single IDT for all CPUs, but that
    can't work, since we need different tasks for the double fault interrupt
    vector.
  - Set the per CPU double fault task gates correctly.
  - Renamed set_intr_gate() to set_interrupt_gate and set_system_gate() to
    set_trap_gate() and documented them a bit.
  - Renamed double_fault_exception() x86_double_fault_exception() and fixed
    it not to use smp_get_current_cpu(). Instead we have the new
    x86_double_fault_get_cpu() that deducts the CPU index from the used stack.
  - Fixed the double_fault interrupt handler: It no longer calls int_bottom to
    avoid accessing the current thread.
* debug.cpp:
  - Introduced explicit debug_double_fault() to enter the kernel debugger from
    a double fault handler.
  - Avoid using smp_get_current_cpu().
  - Don't use kprintf() before sDebuggerOnCPU is set. Otherwise
    acquire_spinlock() is invoked by arch_debug_serial_puts().

Things look a bit better when the current thread pointer is broken -- we run
into kernel_debugger_loop() and successfully print the "Welcome to KDL"
message -- but we still dereference the thread pointer afterwards, so that we
don't get a usable kernel debugger yet.

cc77aba101 * Allocate a separate double fault stack for each CPU.
* Added x86_double_fault_get_cpu(), a save way to get the CPU index when in
  the double fault handler. smp_get_current_cpu() requires at least a somewhat
  intact thread structure, so we rather want to avoid it when handling a double
  fault. There are a lot more of those dependencies in the KDL entry code.
  Working on it...

c32499b4f7 * Since the file_map reports its chunk with a file system specific alignment, we
cannot assume that the file is that long - we need to check for the actual
  file size specifically, and then clear the extraneous bytes based on that one.
* This fixes seeing old file left-overs in the space beyond the file size in
  mmapped file. Thanks to Oliver who provided me with a nice test program to
  reproduce this problem (this should also fix gcc's fix_includes app (although
  I wonder what it does if a file actually ends on a page boundary).
* Also fixed a bug in precaching that would cause the last page of the cache
  to be discarded, causing it to be re-read later on.
* Moved partial page clearing into its own function
  read_pages_and_clear_partial(), even though it's currently only used once.

d829579dc0 mmlr + bonefish:
Moved the static variables for managing the tracing buffer into a separate
area. The area is mapped at one of a few possible physical addresses and can
be found again when rebooting. This allows us to resurrect the tracing buffer
from the previous session, which could help tremendously when tracking certain
bugs (like triple faults). There's very little checking done yet, so it is
probably not as robust as we would wish it to be.

0b11ecb18c * Always include the public arch_debugger.h headers. The structures defined
there are prefixed with the respective architecture name. Useful for remote
  debugging a different architecture.
* <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it
  isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
  bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
  it reinits the FPU after saving the state. This resulted in weird results
  when debugging functions using the FPU. We now use fxsave, if available.
  Otherwise fnsave + frstor should be used -- not fully implemented yet.
  Same for arch_set_debug_cpu_state().

c755ecfe96 * Added an emergency key mechanism to the kernel, inspired by Jan Klötzke's
patch from about a year ago (I couldn't use any code of his yet, though,
  but there are a few things left). The emergency keys are triggered by
  pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
  the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
  emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
  easy anymore to "crash" Haiku if you don't want to.
* Right now, the PS/2 driver, and the pre-input_server in-kernel debugger
  keyboard mini-driver support this, USB not yet.
* Minor cleanup.

7f96148cac Patch by Bryce Groff with changes by myself:
* Added missing name parameter to the partitioning system module child creation
  and child creation validation hooks. Pass the name to them.
* Added BPartitionParameterEditor interface, which is/will be used for editing
  disk system specific parameters.
* Implemented partition parameter editors for BFS initialization and Intel
  partition map child creation.
* Fixed the incorrect supported child partition type iteration in the Intel
  partition map add-on. It does now return actual types.
* Handle the "active" flag parameter in the Intel partitioning system module.
* DriveSetup:
  - Replaced the "Create" submenu by a simple menu item. The type can now by
    chosen in the dialog.
  - Make use of initialization and child creation parameter editors. Some
    non-generic code has been moved to the respective editor implementations
    (BFS, intel partitioning system).

  from the buffer area.
* Fixed leak in SharedImage::Init().
* Made the symbol retriever more smart when it deals with kernel images; if the
  image ID is no longer available, it will now use the path based image symbol
  iterator (and also adds the boot kernel path, in case the module don't have
  one).

a365e1cfbb Patch by Bryce Groff, some changes by myself:
* devfs:
  - devfs_[un]publish_partition(): They no longer get the partition path as
    parameter, but rather the device path and the partition name.
  - Added devfs_rename_partition(), which renames an already published
    partition node.
* KPartition/KDiskDevice:
  - Replaced the fPublished flag by fPublishedName, the name under which the
    partition is published. This simplifies UnpublishDevice() and makes it
    practically infallible.
  - Added GetFileName(), which only returns the partition's file name.
    Simplified GetPath() by using it.
  - When a partition is added/removed the subsequent sibling partitions get a
    new index. Now we also rename their published device nodes (and those of
    their descendents). When something goes wrong we unpublish the concerned
    partition's device to be on the safe side. Would be a shame to accidentally
    format the wrong partition, eh? :-)

be1f4fe800 * find_symbol_breadth_first() didn't ever set _foundInImage, although
it's signature indicates that it should - the callers just never use
  the value currently, so it caused no harm
* squashed a TODO in the runtime_loader about the resolving strategy
  for undefined symbols in add-ons: I've implemented the breadth-first
  strategy (leaving out the add-on itself), as that one made most sense to
  me.
This avoids loader problems with older optional packages of Pe on gcc4, as some
add-ons (e.g. "Expand Tabs") could not be loaded due to them containing undefined
symbols that are found in second level dependencies (libstdc++.so in this case).

Ingo: please review.

181593ba0b * Properly document why fs_write_attr() does what it does.
* As even the author of fs_attr.c was trying to use fs_write_attr() in an
  unsupported way in the cp copy_attributes() implementation, try to be
  more forgiving and support writing attributes at an offset. The method is
  required to behave inconsistent in that replacing bytes at offset 0 is
  not supported as replacing bytes at any other offset. Writing at offset 0
  will clobber the existing attribute to stay compatible with BeOS.

NOTE: BFS itself still does not support writing attributes at an offset which
are withing the "small data section". To work around this problem, programs
which copy attributes in a loop must make sure that their buffer is large
enough that such "small data section" attributes require only one loop
iteration.

e0965f2727 * reload_driver() now also checks if the binary node changed, and will update
the node listener, to make sure it won't lose track.
* The DriverWatcher now also listens for B_ENTRY_REMOVED. This causes drivers to
  be unpublished even if they are only symlinked.
* However, to detect new drivers in a symlinked location, we'd need special
  support for those, and also need to watch the parent directory of the symlink
  target - this is close to overkill, so I stayed away from implementing that
  for now :-)

bbe9c7b15e Rewrote user_debug_thread_deleted():
* It was broken since the support for debugger handovers. Using
  debugger_write() couldn't work, since the thread didn't belong to the
  debugged team anymore (but to the kernel) and thus getting the debug info
  for team would always fail. This makes B_DEBUGGER_MESSAGE_THREAD_DELETED
  notifications work again.

568ade58d0 User debugger support:
* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
  not running thread. Introduced arch_get_thread_debug_cpu_state() for that
  purpose, which is only implemented for x86 ATM (uses the new
  i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
  register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
  after a instruction breakpoint debug exception. This should prevent
  breakpoints from being triggered more than once (e.g. when the breakpoint is
  on an instruction that can cause a page fault). I still saw those with bdb
  in VMware, but that might be a VMware bug.

f835a75f31 Make two runs of MTRR setting when setting memory ranges to write-back. At the
first run only set up uncacheable MTRRs and in the second run set the write-back
ones up. If this order is not followed, we could set too large ranges to
cacheable first and then limit it back to uncacheable later. On systems with
enough physical memory this would lead to a temporary situation in which areas
become cacheable that must not be, resulting in system hangs or other unexpected
behaviour. Fixes last part of #4018.

boot device is actually read-only (even if it's using the write overlay).

* Made swap_file_{add|delete}() take a const char* path - there was no reason
  this was writable, and this also avoids casting away the const when adding
  the default swap file.

eb0262fc4c * Reworked vm_soft_fault() and friends:
- While walking down the cache chain, we keep all upper caches locked.
  - When we have to unlock -- when waiting for a busy page or reading a page in
    -- we unlock completely, including the address space, and restart
    vm_soft_fault().
  - Folded fault_get_page() and fault_find_page() into one.
  This simplifies and improves things considerably:
  - We no longer need dummy pages.
  - We no longer need vm_area::no_cache_change.
  - #2710 is fixed, since we no longer hold the address space lock while
    waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
  is already mapped at the address. If it is already our page, we just change
  its protection. If not, we unmap it first. Fixes race conditions when multiple
  threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
  mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
  vm_translation_map::protect() call.

  (as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
  compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
  stat_beos*, and and made it private. Added a new version (using up a
  reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
  for sake of binary compatibility. This breaks source compatibility, though,
  which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
  BRefFilter.

a5dbd78b7a * Since PrecacheIO is used as asynchronous callback object, we must not access
it anymore after having called vfs_asynchronous_read_pages().
* Now, Prepare() does all the preparation work, and ReadAsync() does the actual
  work - this must be called without having the cache locked. This also fixes
  another bug where the callback would be deleted twice in case the I/O request
  failed.
* This fixes bug #3847.

d5ad762913 Fixed several problems of the prefetching code:
* Did claim to have reserved pages when calling vm_page_allocate_page(), but
  didn't have any (copy&paste bug). We cannot use it without reserved pages,
  as we need to call vm_page_allocate_page() with a cache locked.
* No longer use low_resource_state() to determine whether to precache or not,
  but use the new vm_page_num_used_pages() instead.
* Also don't (try to) precache when the cache already has more than 2/3 of its
  pages to safe some unnecessary work.
* The size to precache was limited to the file size incorrectly.
* When precaching failed, the cache reference was not released.
* The precaching started one page too late, causing bug #3835.
* Reenabled precaching.

* Implemented a way to do asynchronous pre-fetching when mapping files.
* There are slight code duplications in some places that could benefit
  from cleaning up, but nothing too bad.
* Implementing smarter ways to trigger prefetching and more analysis of
  the situations in the kernel would be nice. Currently up to 10 MB
  of every mapped file are pre-fetched without further analysis.
* The speed improvement is nice for certain operations. On our test
  system (real hardware), Firefox took 9 seconds from being launched
  to display a window. Now it takes 5 seconds. Both measurements
  right after booting. The same system took 35 seconds from launching
  Haiku in the GRUB menu to displaying the Tracker desktop background
  image. Now it takes 27 seconds.
* We didn't have the chance to check out the effects of this on the
  CD boot, but potentially, they could speed it up a lot.

227fe7d34a * Scheduler/wait object listener:
- Moved scheduler listening interface to <listeners.h> and added more
    convenient to use templatized notification functions.
  - Added a listener mechanism for the wait objects (semaphores, condition
    variables, mutex, rw_lock).
* system profiler:
  - Hopefully fixed locking issues related to notifying the profiler thread
    for good. We still had an inconsistent locking order, since the scheduler
    notification callbacks are invoked with the thread lock held and have to
    acquire the object lock then, while the other callbacks acquired the object
    lock first and as a side effect of ConditionVariable::NotifyOne() acquired
    the thread lock. Now we make sure the object lock is the innermost lock.
  - Track the number of dropped events due to a full buffer.
    _user_system_profiler_next_buffer() returns this count now.
  - When scheduling profiling events are requested also listen to wait objects
    and generate the respective profiling events. We send those events lazily
    and cache the infos to avoid resending an event for the same wait object.
  - When starting profiling we do now generate "thread scheduled" events for
    the already running threads.
  - _user_system_profiler_start(): Check whether the parameters pointer is a
    userland address at all.
  - The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
  since the caller has to ensure that the semaphore exists and continues to
  exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
  profiling changes. The latter prints the number of dropped events, now.

146f113fec Fixed issues with the scheduling events. In the listener callbacks we
potentially want to notify the profiler thread (i.e. wake it up), which can
cause another scheduling event notification. That is we have to make sure that
event buffer is in a consistent state at that point (i.e. wake up the thread
at the very end of the callbacks). Furthermore the ThreadEnqueuedInRunQueue()
callback can be called with spinlocks besides the thread spinlock being held. In
particular waking up threads also happens in the condition variable code with
a static spinlock being held. Trying to notify the condition variable the
profiler thread is waiting on in such a case would be a guaranteed deadlock.
Hence we avoid doing that, now.

3539fc6e19 page writer:
* When writing a page failed it is not a good idea to re-enqueue it at the tail
  of the modified queue, since that is definitely behind the page writer's
  marker and the page would be picked up again before reaching the end of the
  queue. If that happened with more than 256 pages, the page writer would keep
  picking up only those non-writable pages and make no more progress.
* When selecting pages also skip temporary pages, if there's no more swap space
  available, since trying to write those pages would most likely fail anyway
  (triggering the first problem).

48b0c6f93a debug_trap_cpu_in_kdl(): If the CPU running the kernel debugger exited and

now call smp_intercpu_int_handler() in the loop and guard the function from
being re-entered. This also has the advantage that we can execute code on all
CPUs in the kernel debugger, if we have to.

efd536ff89 * Cleared up a misconception in the notification mechanism. We already had
methods that used an "event mask" field. There was no need to introduce
  a "flags" field for the same purpose.
* Renamed protected DefaultNotificationService methods (removed "_" prefix).
* Adjusted the code providing a notification service accordingly.
* Changed the event message several notification services generated by renaming
  the "opcode" field to "event".
* Implemented the TEAM_ADDED event and also added a TEAM_EXEC event.
* Added notifications for threads and images.
* Added visitor-like iteration functions for teams, threads, and images.

page failed since the cache has been shrunk, we need not only remove the
  page from the cache, we also need to remove all of its area mappings and
  free it. Not removing the area mappings might have been the cause of #3110,
  not freeing it would cause it to be leaked for good.
* vm_page_write_modified_page_range(): When writing failed for another reason
  and the page wasn't in the modified queue before, we would lose the info
  in which queue it was before and setting the page state to modified would
  assume the active queue. This could potentially screw up our page queue
  structures.

* We started the "main2" thread too late. Since the scheduler was already
  started on all CPUs, the idle thread could wait (for a mutex) while
  spawing the "main2" thread. This violated the assumption in the scheduler
  that all idle threads would always be ready or running. We now create the
  thread while the kernel runs still single-threaded.
* scheduler_start() is now invoked with interrupts still disabled. We enable
  them after the function returns. This prevents scheduler_reschedule() from
  potentially being invoked before scheduler_start().

* Also took the liberty to rename our boot loader to haiku_loader, since I had
  to update the nasm binary anyway. Updated the assembly sources to nasm 2.0.
* I haven't found where the synth location in the MIDI code is specified,
  though.
* Also, NetBootArchive, and FloppyBootImage haven't been updated yet. Will do
  so next.
* Some optional packages still put their license to beos/etc/licenses. I didn't
  update them yet, as we'll probably do so anyway at some point. Also, I think
  we might want to introduce a common/data/licenses instead for those.
* If you encounter any problems, please tell!

14df3c2bed Various tweaks - 1) while enqueued, keep track of which run queue a thread is in on the scheduler data structure, and use this information so that set_thread_priority doesn't have to search every CPU to find the thread. Also slightly tweak the enqueue and steal operations to take advantage of some of the stats we're now tracking, and experiment with variable quantum sizes for low priority CPU bound threads. Still lots of work to do with respect to balancing and/or affinity though.

d30acbf30b Patch by maxime.simon: Don't allow to enter sub-menus by the space bar anymore.
This allows to have the first item selected when entering a menu, since still
pressing space would not enter it unintentionally anymore, in case it's a sub-
menu again. Even though it makes some sense to have "Continue booting" selected
by default, it somehow feels more natural to have the first item always selected
instead. Thanks!

39d58e2f49 Experimental approach to tackle the problem with Be's negative error codes and
ported software:
* If the macro B_USE_POSITIVE_POSIX_ERRORS is defined the POSIX error code
  constants (ENOMEM, EINTR,...) will have positive values.
* Introduced the macros B_TO_{POSITIVE,NEGATIVE}_ERROR() which do convert a
  given error code to a positive/negative value.
* Added static library libposix_error_mapper.a that overrides all POSIX
  functions (save the ones I forgot to add :-)) directly meddling with error
  codes (having them as parameter or returning them) dealing with the
  positive<->negative error code conversions. The functions have hidden
  visibility, so they affect only the shared object they are linked into.
* So ideally all one has to do is to build a ported software with
  -DB_USE_POSITIVE_POSIX_ERRORS and -lposix_error_mapper and be good with
  respect to error code problems.
* Potential issues:
  - When mixing ported and Haiku native code, i.e. using Haiku native code in
    a ported software or using a ported library in a Haiku native application
    care must be taken to convert error codes where the two interface. That's
    what the B_TO_{POSITIVE,NEGATIVE}_ERROR() macros are supposed to be used
    for.
  - A ported static library can obviously not be linked directly against
    -lposix_error_mapper. The shared object linking a against the ported static
    library has to do that. The previous point applies when that causes mixing
    with Haiku native code.
  - When dependent ported libraries are used probably all of them should use
    the error mapping.

Comments welcome.

24fde47c7a Introduce an experimental new scheduler intended to work fundamentally the same as our existing one, but with various optimizations to better handle the SMP case:
1) We now maintain a runqueue per CPU, rather than a single global shared queue. Idle threads are segregated into their own queue for simplicity.
2) Enqueueing threads is now somewhat more intelligent - if the thread is pinned, it is always enqueued onto that core. Otherwise we enqueue it on whichever CPU it previously ran, unless it either hasn't run before, or that core has been disabled via ProcessController. If so, we try to enqueue it on whichever core has been the most idle recently.
3) The above allow various simplifications to thread scheduling. Pinned threads and/or disabled cores are now no longer special cases that need to be dealt with. If a CPU has no threads ready, it looks for another one to steal a thread from, though that part still needs some tuning along with enqueueing for load balancing purposes.

The chief aim here is better load balancing and support for soft affinity. However, at the moment the overall behavior still exhibits some regressions compared to the old scheduler, so it's disabled by default. If you wish to experiment/debug with it, instructions for enabling it can be found in scheduler.cpp. Much thanks to Ingo, Axel and everyone who's helped with either code review/advice or testing so far.

f528e1ad7a Fix two more problems in the messaging service:
1) When searching the area for a place to allocate the next command, the case of the first command being the same as the last command (as is the case after adding the first message) was not correctly considered. This prevented a given area from ever containing more than one command.
2) The size of a command was incorrectly word-aligned. Rather than aligning to 32-bit boundaries, the size was truncated to between 1-3 bytes, leading to command corruption once multiple messages were in the area, eventually causing registrar to crash while retrieving the messages.

Combined these two changes result in us no longer constantly allocating/destroying areas during heavy node monitor activity.

75d1cb286f The loop that looks for the next area to add a message to has a somewhat fatal flaw: it checks for a non-zero area size (which is always set to the physical size of the area rather than the number of message commands stored within it). As a consequence, areas would never get cleaned up once allocated, which lead the kernel to steadily bleed memory if any reasonable level of node monitoring activity was going on. We now check whether or not the area's command count is non-zero instead, and use that as the criteria for selection. Fixes ticket #3518.

6eba063647 * Added simplified possibility to schedule UHCI transfers from within KDL.
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
  when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
  to ensure that reading characters always goes through the kernel debugger
  add-ons and the other methods.

This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
   be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
   also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
   time between initializing USB and when usb_hid is opened by the input_server
   there is no keyboard support.

Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.

On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.

Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

3684e40bb8 * Introduce a (private) flag B_NO_HANDLED_INFO for install_io_interrupt_handler.
It causes the interrupt handler to be inserted at the very end of the list
  instead of at the top. It is intended to be used as a workaround when a
  interrupt handler cannot know if it actually handled the interrupt. This
  should never be used by native drivers. Also if we know that the result is
  not valid because of this flag we won't disable the vector in case we count
  many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
  instead of the doubly linked one used with insque and remque as it greatly
  simplifies things for such an easy use case and is more compact.

* Implement mounting layered filesystems. Specifying multiple filesystems

  corresponding filesystems to be mounted at that layer.

  fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
  use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
  flags field of a fs get_vnode call. A filesystem can use this flag to indicate
  that it doesn't support the full set of fs features (attributes, write support)
  and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
  on a filesystem where attributes aren't supported. It does currently only
  support reading attributes/attribute directories though. All other calls are
  just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
  is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
  so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
  later to only trigger where there are features on a CD that need emulation
  at all.

If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

b36570e51f Do proper unlocking of the KPath when find_directory() fails. This should help with CD boot where find_directory() can't create folders on a read-only media.

d9c6f9a92c Remove separate GCC4 versions of add_debug_command()/remove_debug_command() and
add the const in any case. As Axel points out these are C functions and we do
not affect binary compatibility by changing their signature.

d0eaec3086 Fix more operator precedence errors. These do not do what you'd expect at first
sight. The comparison operator takes precedence over the binary ones.

c33667d400 Fixing warnings under GCC4 in preparation to enable -Werror there as well:
* Replaced the use of offsetof() for structs that aren't PODs. Add a
  offset_of_member() macro to util/khash.h because that's what it's used for
  in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
  GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
  it pointed out at least one bug that is fixed here as well.

47bc666311 The assumption that the program image is not used for relocation of
dlopen()ed objects was incorrect. This should fix problems with ports of
software with a plugin/add-on interface.

74a366707f When linking against libgcc already don't include these symbols. Otherwise we
get multiple definitions of them when building with GCC4 on a GCC4 host.
With that we can now build completely on a GCC4 host with native GCC 4.3.3.
