28dd47de9e Fixed the last commit: after we have acknowledged the interrupt, the
interrupt service register bit is never set, anyway...
Thanks to Korli for reporting.

49cb24e833 Added workaround for spurious interrupts on line 7/15 - they are no longer
forwarded to the standard interrupt handler. Untested, though.
For more information on the subject: http://www.ggd.nsu.ru/~serg/bsdfaq/part3.html#316
Some cleanup.

ada5975312 fs_mount() and get_file_system() can now both handle file system names
in the form "bfs" and "file_systems/bfs/v1".

47f39c93cb Merged the disk device manager module interface for file systems with the
VFS's interface, so that a file system only has to implement one interface.
As a side effect, the automatic file system detection may now work (not yet
tested, though).

Not yet used, though - we probably need to rearrange the source files a bit.

errors. Also made the VM headers C++ safe.

8f8d46a3ff vm_put_area() now gives feedback wether it deleted the area or not (it
will return true in the former case).
vm_delete_areas() is now using this information to print out a warning
in this case (so that a missing vm_put_area() can now be found easier).

4393552b4d The heap is now located at 384 MB, and creates a reserved range that spans over the
following 1152 MB - that area only guarantees that the heap can grow this much before
the application need the memory for something else. And even then, the heap range
is reused from top-to-bottom, allowing for maximum heap usage. Of course, if the
memory after the heap range is not claimed yet, it can still be claimed by the heap,
too. Added new syscall to create the reserved range.
Fixed a bug in vm_delete_areas(): when it removed reserved areas, the area list
could get messed up.
Fixed a bug in resize_area(): resized areas could never be deleted (missing vm_put_area())!
resize_area() now supports reserved regions (but not perfectly yet, see ToDo items).

a3e9996e9d Added support for special reserved address ranges: they will be used
only if memory becomes tight, and then the range is used from end to
start.
This is useful to reserve heap address ranges.

ccc8865ba2 Added an additional flag B_OVERCOMMITTING_AREA (currently to be specified
along the protection flags).
Changed the handling of B_STACK_AREA types and anonymous vm_areas: now
every area can overcommit if B_OVERCOMMITTING_AREA was specified.
B_STACK_AREA areas are still automatically overcommitting, but
B_KERNEL_STACK_AREA areas no longer.
vm_store_anonymous_noswap.c now only tests for guard pages if there were
any specified which is only done for B_STACK_AREA areas.

(right now, it's still malloc/free, just encapsulated in an allocator class).

cbd1d9977f Changed all _kern_*() calls to use KPath instead of a path buffer on the stack.
This reduces the stack usage quite a lot, and since file system calls could be
nested (for example, a mounted image on a volume), definitely a must, too.
Might be a good idea for user calls, too, though, although it's not urgent.

0953c83ebd Fixed another bug: after a partition had been mounted, it was only marked
mounted, but no one told it about its volume ID - that caused "mountvolume"
not to be able to return a valid mount point.

file system has been mounted, it would have crashed (that for example
happened if you deleted the kernel settings file...).

b20667b35b {install|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag.
Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
  described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
  it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
  is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
  (though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
  "status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
  equivalent (and private) are_interrupts_enabled()

b51d2e941a Now uses the ring_buffer implementation instead of cbuf.
Decreased the pipe buffer to 32768 bytes (it's 4096 on BeOS).
pipefs_select/deselect() did no locking.
Switched to using the BenaphoreLocker where possible.

900849fa0d Since objects/.../system/kernel is now a directory, the kernel target is now
called kernel_${arch} like on disk. A "jam kernel" will still work, though.
Also updated all those Jamfiles I forgot to update before.
Since makehdimage now runs through (and even builds a working image), I guess
most of the consequences of the "kernel/core" -> "system/kernel" rename task
are solved.
