1d099cad03 Patch by Bryce Groff: Allow passing an ID of any partition contained in the
disk device to the locking functions, not only the ID of the disk device
itself.

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.

eb26e782f3 * Decoupled block_cache_used_memory() from the sCachesLock - this should fix the
UI freezes (ActivityMonitor and ProcessController both use get_system_info() a
  lot), although this is only the symptom of another problem.
* The downside is that the block cache usage information isn't as up to date as
  it was previously - it's updated by the block write/notifier thread now (worst
  case every 2 seconds).

5efec82035 * Fix KDL output to use kprintf instead of dprintf.
* Make the allocations command available even without leak checking. The sizes
  that are dumped aren't as accurate without leak checking info, but having the
  address and max size is already helpful.

2c8ad7ab3e * If the fs_io() hook failed, we need to check if the request has been notified
about it (there is also no public API to do that in the FS yet).
* This could have caused bug #2719, although the specific reason why the FS hook
  failed remains unknown. At least it won't hang in this case anymore.

5147963dcd headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the
class to BOpenHashTable and changed the interface slightly so that HashTableLink
became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.
