08da6fccdd Introduced a sane concept of ownership for the team_args structure: now load_image_etc()
and exec_team() have an additional "kernel" argument and will copy the arguments
themselves (or rather, delegate that to create_team_arg()).
When team_create_thread_start() is called, it will take over ownership and is
responsible for deleting it - this also fixed a memory leak in case the user
stack area couldn't be created.
Also changed comment after exit_thread(): since this call only delivers a signal, the
code after it will still get executed.
This fixes the crashing symptom of bug #50.

f10cba9aec Changed get_mount() to return a status code instead of just the mount or NULL.
Some fields of fs_mount were not properly initialized when FS's mount function
was called, and therefore, could let get_mount() return a mount structure that
was not yet read for public consumption (this should fix bug #51).

d86d4063b0 thread_create_thread_start() is a thread_func and therefore returns int32 not status_t
(that's what our headers say).

43ffbcc46e If a page fault happens from within the kernel debugger, vm_page_fault() is no
longer called - instead, it get its own mini page fault handler: if the thread
has a fault handler, that one will be executed.
Exiting the debugger (with the "continue" command) no longer causes the
vm_page_fault() routine to be called if interrupts were disabled.

19dfa58852 add_wall() first added the memory block to the list, and then added the wall - there
was a race condition between that and the wall checker daemon (if enabled): it could
occasionally report an overwritten wall in that very moment.

removed the locking it did, as that doesn't work anymore in the kernel debugger.
The function was not thought to be used outside the debugger, anyway.
Improved usage message from debugger command "ls".

to it - if that page was read from disk unmodified before (or written back in
the mean time), the updated contents coult not be detected, and therefore, were
never written back.

67a7102658 Fixed a pretty fatal bug in the page fault handling: interrupts were enabled
even if "kernel_startup" was "true". Page faults are now no longer allowed
during kernel startup (and could be easily avoided). The only situation where
we accept page faults with interrupts turned off now is during a kernel debugger
session.
Added a command debug_debugger_running() to test for that situation.
kernel_debugger() no longer sets kernel_startup while it's running; there should
be no situation when this could be helpful.
Interrupts are no longer enabled when a page fault happens in the kernel
debugger.
This potentially fixes all sorts of problems, and not only in the kernel debugger,
it could also have affected SMP (will test later).

96643545c5 Removed unnecessary and stupid code - the doubled chain allocation also caused
a page fault during startup, because the chain memory is B_NO_LOCK.

099ceb8f9d map_physical_memory() and its backend vm_map_physical_memory() did not map in the
pages, ie. they considered the areas to be B_LAZY_LOCK. But that doesn't really make
sense and potentially cause page faults where you wouldn't expect them (and where
it's not a good idea to trigger them).
Reworked display_mem() (used by the dw/db/ds commands in the kernel debugger) to
be a bit more sane, improved formatting, and allows it to work on non-existing
memory without a panic.
The "area" debugger command now also accepts an address (contained by the area)
as argument - and it will now always print out an error message if no matching
area could be found.
Replaced all dprintf() calls to kprintf() calls for the kernel debugger functions.

23e13b2e9b The number of semaphores available is now computed based on the amount of memory.
Just like on BeOS, the overall maximum is 65536 semaphores for now - the mechanism
tends to make more semaphores available than the one under BeOS, though (which is
intended).

5b14757a30 We now have a consistent scheme what the file system should do with its root
node: like in BeOS, it *must* own the root node (ie. via publish_vnode()),
unlike in BeOS, it must also drop that reference on unmount (symmetrical
behaviour definitely makes more sense to me than the Be way).
Since all existing file systems for Haiku behaved differently, I brought them
in line (only pipefs already adhered to that new standard for some reason,
rootfs did only released the node, devfs did nothing - despite it's probably
not really useful to be able to unmount them).
fs_mount() will now panic if a file system does not do this correctly (useful
for file system developing).
Unmounting is now theoretically working again: when trying to unmount a BFS
volume, the kernel crashes in the block cache destruction... (but that's work
for tomorrow).

794df3bf25 This removes the inline assembly code for find_thread
from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility, 
_kfind_thread_ is retained. This will fix some compile 
problems, and provides a cleaner OS.h for future Haiku
versions.

99e1c71ee6 - fixed a locking bug in the file cache: get_file_map() could been called with either
only a read lock on the inode, or without a lock at all (in case of prefetching) - it
  is now using the cache_ref's lock to make sure it's retrieved only once and doesn't
  waste/corrupts any memory.
- since that fix made it mandatory to fix write_chunk_into_cache() to not call pages_io()
  while holding the cache_ref's lock (was a to-do item before), I changed it to make
  that possible.
- It now also supports write-through caches in theory - as there is no way yet to tell
  a cache to work this way.
- Optimized for the not so uncommon case of writing the last part of a file that is not
  a multiple of the page size - it won't call pages_io() anymore then, but zero the rest
  of the page directly.
- vm_page_write_modified() is now calling write_page() without holding the cache_ref's
  lock as well.
The updated write_chunk_to_cache() is not so well tested, though, but appears to work
so far.

07810890b5 Entering an empty line to the debugger will no longer match the first best command
available.
Broken escape sequences are now properly ignored (read one character too much before).
Since the current line buffer is part of the history, we now delete that buffer when
crossing the current line again while traversing the history (restoring the former
buffer would be the nicest way, but that would require another empty buffer and more
copying).
Cleanup.

  extents but the first

eab435cd59 vfs_get_vnode_cache() now only allocates a new cache if requested: this
prevents the system to allocate caches for files that don't use or have
a file cache (ie. only those can be mmap()ed!).
Therefore, cache_prefetch() no longer crashes when trying to prefetch
files without a file cache.
read_into_cache() no longer does anything if the requested size is 0.
Fixed a bug in cache_prefetch_vnode(): if the cache couldn't be retrieved,
it put the vnode, but didn't own it (the caller does).

  in those cases. Wouldn't harm, if someone more knowledgable would check

  that was used into x86/arch_int.c.

230a037ed4 Fixed a bad bug in vm_copy_on_write_area(): the area's cache offset was not taken
into account when remapping the pages read-only; it could have overwritten valid
page mappings this way. This was also the reason for the Terminal to crash - it
does now work as it should, although some keys don't work (like tab completion)).
vm_copy_area() no longer always sets B_KERNEL_WRITE_AREA if no kernel protection
was specified, but mirrors the userland protection (for example, the x86 MMU is
not able to have a page writable in kernel but not in userland). This caused
some areas to be read/write when read-only would have been enough.
vm_copy_area() now panics when vm_copy_on_write_area() fails - that's of course
no real solution, but it's bettern than letting it silently fail.

be22452f3b Apparently, both load_image() and exec*() support running scripts. We do that
now as well.
Also, both functions will now test if the executable exists and is valid; that
way, load_image()/exec*() can catch many errors without having to create a new
team (or erase the current one - an exec*("my invalid app") might now return
with an error).

of the search paths, and will also check user permissions upfront.

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).

kernel_debugger() didn't do enough before; panic() did all the work - but

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.

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.

mounted, but no one told it about its volume ID - that caused "mountvolume"
not to be able to return a valid mount point.

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.
