88b29adcbd VMCache::Resize(): When shrinking the cache unmap the pages we're removing.
Theoretically, not doing that could have caused still mapped pages to get
into the free queue. This could have been a cause of #3110, but the reported
circumstances don't look quite fitting.

c39ecc608f * If getting a new port message failed, we must release the port's write sem
again, or else the port loses capacity.

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.

2d8073a9dc * Added a TODO about a problematic use of vm_page_allocate_page() in combination
with vm_cache_acquire_locked_page_cache().
* Added new function vm_page_num_unused_pages() which returns the pages that are
  actually completely free and unused.

12442ce54b - add a gBootDriveAPI variable telling which method was used to load,
- move gBoot* out of the boot sector,
- fix the FAT params to actually indicate 1.44kB floppy,
- fix the FloppyDrive class to also use 18 sectors/track, so now tarfs won't get data from start of disk when on the middle.

eb2bd0e8e3 axeld:
* 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.

- print a dot / sector read in the great tradition of bootloaders,
- set gBootedFromImage correctly,
- fix the script, make it jam later on.

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.

4a559f388b simple_enqueue_in_run_queue(): Between having found the insertion point and
manipulating the queue is a particularly unsuitable place for calling the
listeners, as they wouldn't be allowed to e.g. unblock threads, since that
would screw the run queue.

8b3b05cbf9 Synchronize the TSCs of all CPUs early in the boot process, so system_time()
will return consistent values. This helps with debug measurements for the time
being. Obviously we'll have to think of something different when we support

8a26f35a6d * Sequential write accesses were never detected, due to an incorrect check.
* The previous code would have scheduled a single page to be written out (if it
  would have ever been triggered), now we schedule the complete previous write
  access. This greatly speeds up a "dd if=/dev/zero of=test ..." beyond the
  size of available memory.

* Added scheduling events to the system profiling interface. Those are pretty
  much the ones recorded when scheduler tracing is enabled. Still missing are
  the "wait object" events that allow to interpret what a thread is waiting
  for.

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
re-entered it fast enough, we wouldn't leave the loop and thus cause a
deadlock, since we wouldn't process the ICI message telling us to halt. We do
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.

90d46a5c43 * Fixed the "qOffsets" return value. At least how I understand the
documentation the segment offsets it shall return are relative to the
  address specified in the program header.
* Added "qSupported".
* Added the mandatory commands and some additional ones. Partially implemented
  only.

8c91d29b34 * PageWriterRun::Go(), vm_page_write_modified_page_range(): When writing the
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().

317bd7dda3 * Changed directory structure as suggested on the mailing list.
* Made the TimeZoneView less error prone, and also actually use Haiku code (the
  previous check didn't work since it used #if, not #ifdef).
* 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.

  corresponding filesystems to be mounted at that layer.

00405f2286 * Add an additional argument to get_vnode() that gets the fs_vnode_ops of the
node. That is needed for a layered filesystem to be able to construct a full
  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.

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.

0c85bd054e * Reworked undefined symbol resolution in the runtime loader. Got rid of
the per-root-image breadth-first sorted image array. Instead we have a
  per-image hook function to resolve the symbols. The default function
  uses the sLoadedImages list directly, which is breadth-first sorted
  anyway. There's also a BeOS function for old-style symbol resolution
  and one for add-ons, which lacks a proper implementation yet (just
  uses old-style ATM).
* Made the dl*() functions POSIX compliant:
  - dlopen() does no longer use load_add_on(), but loads the object as a
    library. It also properly supports a NULL name, now -- the previous
    "_APP_" work-around did only work, if this soname was set on the
    program (unlikely for programs using this API).
  - Implemented RTLD_{GLOBAL,LOCAL}.
  - dlsym() looks up symbols properly now, i.e. not just in the given
    image, but breadth-first for an actual image or in load order for
    the global scope. It also supports the not-quite POSIX RTLD_DEFAULT
    and RTLD_NEXT extensions. Our RTLD_NEXT finds more symbols than in
    Linux (also in later dlopen()ed libraries), but that should be fine.

5074333ded * Updating glob() actually broke it, since Haiku does have broken mbrtowc(),
and wcrtomb() functions. I worked around the issue, and added a build
  warning so that we don't forget to change it back once we have working
  versions of those.
* This lets apps like "ftp", and "sftp" work again.

2c1e463c7e * Removed B_{MIN|MAX}_PRIORITY from OS.h - they were never really intended
as public defines. They are now called THREAD_{MIN|MAX}_SET_PRIORITY to
  better reflect what they are for. Minimum priority is now 1, ie. you no
  longer can set another thread to the idle priority. This fixes part of
  ticket #2959.
* set_thread_priority() will no longer allow to change the priority of the
  idle thread to something else. This fixes the rest of ticket #2959.
* Automatic whitespace cleanup in OS.h.

a26045b7a6 * cache_detach_sub_transaction(), and cache_abort_sub_transaction() now support
discarded blocks correctly as well.
* cache_detach_sub_transaction() left cached_block::original_data unchanged even
  if the parent data was to become current (in case the sub transaction didn't
  change the block yet). This could cause outdated blocks to be written back.
* cache_detach_sub_transaction() also set cached_block::previous_transaction
  for all blocks, not just the ones with a previous transaction. This could
  cause blocks to be written twice for no reason.
* cache_start_sub_transaction() did not change the num_blocks count for
  discarded blocks.
* block_cache_discard() now panics if the block was already changed in the
  current transaction.
* Improved test application, added more tests, revealing the above bugs in
  cache_detach_sub_transaction().
* Minor cleanup.

  LD_PRELOAD can contain a whitespace-separated list of shared objects
  that will be loaded before the program. This allows to replace
  symbols without changing the executable or libraries.
* Resolved TODO in load_program() regarding the order of remapping the

9a42ad7a77 When switching to a kernel thread we no longer set the page directory.
This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference
counted now.

This optimization reduces the kernel time of the Haiku build on my
machine with SMP disabled a few percent, but interestingly the total
time decreases only marginally. Haven't tested with SMP yet, but for
full impact CPU affinity would be needed.

53892c92a0 * Replaced scheduler_remove_from_run_queue() by
scheduler_set_thread_priority(). Setting the thread priority was the
  only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
  an operation vector now, which is initialized at kernel init time.
  This allows for picking the most suitable scheduler for the machine
  (e.g. a non-SMP scheduler on a non-SMP machine).

05fd6d79fe Fixed bug introduced in r28223: The counter whose modulo was used as
index into the sLastCaller array is vint32, so after overflowing the
modulo operation would yield negative indices. This would cause the
256 bytes before the array to be overwritten. Might also be the cause of
#2866.

47c40a10a1 * Prefixed memset_physical() and memcpy_to_physical() with "vm_",
added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
  added respective functions to the vm_translation_map operations. The
  architecture specific implementation can now decide how to implement
  them most efficiently. Added generic implementations that can be used,
  though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
  flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
  Instead it returns an implementation-specific handle that has to be
  passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
  and *_debug() variants, that work only for the current CPU,
  respectively when in the kernel debugger. Also adjusted the
  vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
  tree.
* Also adjusted the m68k and ppc implementations with respect to the
  vm_translation_map operation changes, but they are probably broken,
  nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
  suboptimal in any case. For systems with small memory it is too much
  overhead, since one can just map the complete physical memory (that's
  not done yet, though). For systems with large memory it counteracts
  the VM strategy to reuse the least recently used pages. Since those
  pages will most likely not be mapped by the page mapper anymore, it
  will keep remapping chunks. This was also the reason why building
  Haiku in Haiku was significantly faster with only 256 MB RAM (since
  that much could be kept mapped all the time).
  Now we're using a different strategy: We have small pools of virtual
  page slots per CPU that are used for the physical page operations
  (memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
  Furthermore we have four slots per translation map, which are used to
  map page tables.

These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.

3b839d857b The fs_mount structure now has a constructor/destructor and is used with new and
delete. Therefore the constructor/destructor of the contained EntryCache is also
called. The manual call of the destructor to the OpenHashTable inside the
EntryCache was therefore superflous and the destructor would be called twice,
leading to bug #2869.

7ab39de989 * Removed unused SMP_MSG_RESCHEDULE ICI message.
* Introduced flag "invoke_scheduler" in the per CPU structure. It is
  evaluated in hardware_interrupt() (x86 only ATM).
* Introduced SMP_MSG_RESCHEDULE_IF_IDLE message, which enters the
  scheduler when the CPU currently runs an idle thread.
* Don't do dprintf() "CPU x halted!" when handling a SMP_MSG_CPU_HALT
  ICI message. It uses nested spinlocks and could thus potentially
  deadlock itself (acquire_spinlock() processes ICI messages, so it
  could already hold one of the locks). This is a pretty likely scenario
  on machines with more than two CPUs, but is also possible when the
  panic()ing thread holds the threads spinlock. Probably fixes #2572.
* Reworked the way the kernel debugger is entered and added a "cpu"
  command that allows switching the CPU once in KDL. It is thus possible
  to get a stack trace of the thread not on the panic()ing CPU.
* When a thread is added to the run queue, we do now check, if another
  CPU is idle and ask it to reschedule, if it is. Before this change, the
  CPU was continuing to idle until the quantum of the idle thread
  expired. Speeds up the libbe.so build about 8% on my machine (haven't
  tested the full Haiku image build yet).
* When spinlock debugging is enabled (DEBUG_SPINLOCKS) we also record
  the spinlock acquirer on non-smp machines. Added "spinlock" debugger
  command to get the info.
* Added debugger commands "ici" and "ici_message", printing info on
  pending ICI message respectively on a given one.
* Process not only a single ICI message in acquire_spinlock() and other
  places, but all pending ones.
* Also process ICI messages when waiting for a free one -- avoids a
  potential deadlock.
* Mask out non-existing CPUs in send_multicast_ici(). panic() instead of
  just returning when there's no target CPU left.

7b8683b252 Updated write_to_cache() to use physical pages for I/O and the new
{memset,memcpy_to}_physical() functions.
Mapping lots of physical pages at once as done before was an actual
problem on systems with enough RAM, as the physical page mapper can map
only 64 chunks at a time. So multiple threads could play dining
philosophers, each getting only one of two chopsticks, waiting for
another one to be freed.

552c8edcd1 * fs_sync() now holds the sVnodeMutex while iterating over the mount list.
* This has the advantage that we no longer need to call get_vnode(), and
  instead can use lookup_vnode().
* This means at least most of the "corrupted BFS inode" messages should be
  gone; they were produced when fs_sync() tried to get already deleted vnodes.
  This was actually harmless, but doesn't really help in trusting your system :-)
* Also, it no longer tries to write back removed vnodes.
* And finally, it now uses a marker vnode when iterating over the list, so
  that it doesn't need to break out of the loop anymore, and can always sync
  all willing vnodes.

d52718a5f8 Fixed serious race condition: If the thread waiting for a request was
interrupted, another thread closing the other end of the pipe could
invoke thread_unblock() while the first thread already entered
mutex_lock(). This would make the first thread think it successfully
locked the mutex, without removing its (on-stack) wait entry from the
mutex queue, thus leading to crashes.

f73283cf6a When opening mails with slightly larger attachements in Beam, I noticed that
it was quite sluggish. When opening larger mails, like a 1.14 MB mail for
example, it could take almost half a minute until it was displayed. It turned
out that the offending thread was in strstr().
This is an implementation taken from Wikipedia (declared as public domain
there), which makes the mails open instantly. This usecase may have represented
a worst-case scenario for the previous implementation. It may be beneficial to
take a look at more of these string functions, but I am happy for now.

ecb3d008d6 If a device reports no media is present, don't try to get the geometry anyway.
This confused some USB card readers, that would stop working if you still
requested the geometry when they reported no media.
Note the case that the B_GET_MEDIA_STATUS fails (because it's not implemented or
an error occured) is still handeld in _GetMediaStatus() and then we still try to
get the geometry to check for media presence.
This should fix that some USB card readers wouldn't work and should also remove
the wrongly reported size in DriveSetup for CD drives that don't actually contain

1fdc8a49aa * Factored out the demangled function call dump to a print_demangled_call().
* The stack_trace() command now also uses this call by default to give you
  the arguments to all functions in a stack crawl (beware of templates for now,
  though).
* Use the new option '-d' to disable the demangling. You can now also specify
  '-d' in the "call" command which has the same meaning there.
* NULL pointers are now printed as "NULL", and NULL strings are printed as
  well.

ddecb4a7da * Changed the way the demangle functionality works: instead of having a kernel
debugger add-on set a demangle hook, all modules under debugger/demangle/ are
  now considered demangle modules.
* Added another function to the demangle module interface that gives you access
  to the arguments.
* Implemented a demangling module for GCC2.
* The older demangling module is now called "gcc3+", but doesn't support
  getting the arguments yet.
* The "call" KDL command is now using demangling to automatically show you
  the arguments of a call from a stack crawl.
* Minor cleanup.

2716cfd3d7 * Threw away the broken stat() vs. _stat() mechanism to allow for more fields
in struct stat.
* Instead, I followed Marcus' great idea and added a compatibility check in
  the runtime loader: now, R5 binaries (also shared libraries) are detected,
  and they get special versions for stat(), fstat(), and lstat() that return
  the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
  larger stat field for now, as this breaks some of our optional packages.
  So until we rebuild them all, this shouldn't be enabled.
* This should now also be used for BeOS compatibility in libnetwork.so.

74785e79db * Added "from" address space parameter to vm_swap_address_space()/
arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
  vm_translation_map_arch_info indicating on which CPUs the address
  space is active. This allows flush_tmap() to avoid ICI for user
  address spaces when the team isn't currently running on any other CPU.
  In this context ICI is relatively expensive, particularly since we map
  most pages via vm_map_page() and therefore invoke flush_tmap() pretty
  much for every single page.
  This optimization speeds up a "hello world" compilation about 20% on
  my machine (KDEBUG turned off, freshly booted), but interestingly it
  has virtually no effect on the "-j2" haiku build time.
