e970b839a0 Disabled B_USER_CLONEABLE_AREA for now - maybe this should be handled via kernel settings later.

229b2db028 cache_node_launched() is now called later, so that the environment will
be the same for both ways (via load_image() and exec*()).

a69e0ac327 The boot item list was not initialized; this was no problem, though, as
no items can be removed from that list - nevertheless, it's wrong.

183dee22cb Unlike R5, receive_data() could return an error code under Haiku - this
can now only happen if the thread is killed.
_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.

2a1492f0fa Moved the definition of the BlockAddressPool class into block_allocator.cpp, as it's
not used outside of it.
Added tracking for the last transaction in the block cache; that way it can test
if the last transaction has been closed before opening a new one.

584d673049 Fixed various bugs in the block allocator: new free ranges were never added
to the free list, so a new range was started for every allocation (!).
block_range::Free() did not update the chunk's used_mask correctly.

68c1f3d2eb Disabled code that could find newly installed drivers - it's not likely we
will do that anytime soon, and it should be done by using node monitoring,
anyway.
devfs_open_dir() now makes sure the directory contents are up-to-date - this
should fix the app_server device lookup.
Disabled debug output in the read/write hooks to improve its usage.
Renamed part_map to partition.
Minor cleanup.

80f6ef8bd8 Moved load_driver() and load_driver_symbols() over to devfs.
Added new devfs_add_driver() function that the device manager will now call
to register new drivers.
Devfs will now keep a list of known drivers and remembers, if they have
been initialized already - a driver can now safely scan the directory it's
in while being scanned itself without having its hooks called twice.
Devfs is now using a recursive lock instead of a mutex (that's not really
a requirement right now, but would allow us to keep the fs lock during
scanning).

f33c8020e2 Removed debug/console.c, we no longer need it. frame_buffer_console_init() is now
called by debug_init_post_vm().
Since the availability of a blue screen specific getchar() is static anyway, there
is no need for the sBlueScreenGetChar variable (only the message "only serial input
available" gets lost, but since that is platform specific anyway...).
Hello blue screen! We now have an on-screen KDL, to be enabled by the kernel
setting "bluescreen", just like on BeOS.
The blue screen does not yet support any cursor actions or backspace, though (need
to grab some stuff from our console driver).

9a63135f7c Cleanup of the debug stuff, prepared for blue screen debugging.
kernel_debugger() didn't do enough before; panic() did all the work - but
since the former is a public function as well, I moved all the functionality
to it. Also fixed a possible buffer overrun in panic().
Renamed dbg_* to debug_*.
"serial_debug_port" setting did not ignore negative values.

Cleanup of the cookie code, it's now using util/list.h.
Now issues B_STAT_CHANGED notifications when directory entries changed.
rootfs_rename() was completely broken for "inter-directory" movements.

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).

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.

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.

47729f044c Fixed a possible bug in path_to_vnode(): if called before a root
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.

718b5114e0 This should fix the build after all the kernel/system renaming.
If anything is still broken (and was not before :)), please shout.
