b848af2071 Greatly cleaned up the source.
Fixed a bug in sigaction(): it would have crashed with act/oact == NULL (which
is perfectly legal).
Now directly exports the kernel API.
Now has user_*() calls where needed.

6d8aafc66e Added comments to sys_(get|put)env() - please remove them from the kernel.
Renamed team_wait_on_team() to wait_for_team() (more BeOS-alike).
Adapted to other changes (new thread functions).
Cleanups.

dba0db7fbe Fixed all the broken signal stuff. Now correctly calls the user_*() function,
and don't have any functionality at this place.
Added new syscall for set_thread_priority().
Some other changes due to cleanup.
Fixed userland snooze() call.

51cc35a759 Cleaned up the source, rearranged some functions. Now exported functions
have the scheduler_ prefix instead of thread_.
Moved thread_set_priority() back to thread.c where it belongs to.
Added new function to remove a thread from the run queue.
Renamed run_q to gRunQueue.

dc7fb22c07 Forgot to resume the kernel_daemon thread.
Actually never unlocked the daemon's lock (always called mutex_lock() instead
of mutex_unlock()...).

the vnodes of a mount structure).
Removed stubs for send_notification() and notify_listener() (they are now located
in message.c and node_monitor.c).
Added support for the node monitoring service.

(or will be) able to send out BMessages from within the kernel; currently
just prints out what should be done.

4fff689f48 Some minor updates:

a now unused variable, assignments to tss_loaded are now booleans.

20726b7fb1 _create_thread() now correctly allocates the stack with REGION_ADDR_EXACT_ADDRESS
from the USER_STACK_REGION (until B_BASE_ADDRESS is available), made it much better
readable. It now grows from the lower USER_STACK_REGION up to the start of the main
thread's stack location.
Calls arch_thread_tls_init() and accounts for the TLS area in the stack region.
Added some comments, some cleanups.

2a6fbb7f88 Removed some hard-coded values with definitions (mostly USER_x_SEG in arch_x86.S,
and TSS_BASE_SEGMENT in i386_set_tss_and_kstack() (thanks Daniel for pointing this
out)).
Added a arch_thread_init_tls() function which fills the reserved slots - the find_thread()
inline asm in OS.h is finally working.
Added some more comments, resolved the ToDo items from last time :-)
arch_thread_context_switch() now calls set_tls_context() at the correct location.
arch_thread_enter_uspace() now calls set_tls_context() as there is no context
switch in this case for the current thread after TLS has been set up, and it
now gets a pointer to the thread structure directly, and calculates the user
stack top itself, rather than the callee.

19321ae5a8 Temporarily removed arch_selector.c from the build - it's currently not used
at all, and assumes a fixed and wrong number of preallocated GDT entries.

Implemented TLS: there is one GDT entry per CPU. If a context switch happens,
the FS register of the new thread is set to the matching GDT, and the GDT is
changed so that it points to the current thread's TLS storage area.
This area currently resides unsafely at the bottom of the user stack - for
some reason I could not figure out, it doesn't even work correctly most of
the time (it segfaults when accessing a slot via FS). I've added a ToDo item
explaining the situation - hopefully I have more ideas when I slept a bit more...

The GDT is now no longer static in arch_cpu.c and has been renamed from gdt to
gGDT. It's now also referenced in arch_thread.c, and it would make sense for
arch_selector.c to use it as well (instead of another local copy).
arch_cpu_init2() now uses the set_tss_descriptor() inline function and the
TSS_BASE_SEGMENT macro to set up the TSS section. It now also sets up the
TLS segment descriptors (as TSS, one entry per CPU).

Since I removed desc_table from the headers (the GDT is now a (segment_descriptor *)),
I added it locally to arch_int.c.
i386_enter_uspace() now don't set the FS register to 0x23 anymore, since it's
now already set correctly at the end of arch_thread_context_switch().

Some clean-ups.

c0d31b20ab Fixed the detection of page faults that happen while interrupts were
disabled. If a page fault happend while a interrupt handler is executed,
or while a section of code is running with interrupts disabled (with the
exception of the initial kernel startup), the page fault handler will
now panic, to give you the chance to fix the bug.

b9b1c1c4f5 Almost completely rewritten module.c. Locking now works correctly, memory
leak fixed, some other bugs fixed, removed the global queues as there weren't
needed and used at all, moved to the other hash table implementation
(because the new_hash_table stuff was buggy). Should really work okay now :-)

Added the last missing function get_next_loaded_module_name() - I am not
sure the Be version works this way, but we could easily change that after
actually having found out how that one is really working.

3fa1fa66f1 Cleaned up the source, made it compatible with our style guide (i.e. global
variables now have the 'g' prefix).
Fixed a very unlikely race condition in create_sem_etc() (can only happen if
that call isn't used properly).
Fixed some wrong return values (i.e. B_BAD_TEAM_ID wasn't returned anywhere).
Optimized _get_next_sem_info(): it now only grabs the semaphore lock
if it has good reason to do so.
Added some comments.

36cfa7d4f8 The USE_WALL setting currently doesn't work, because

0a2bd16f7d find_mount() must not lock the gMountMutex - the caller must do this; that
also fixed a bug, because fs_read_info()/fs_write_info() already locked the
mutex before calling find_mount().
Implemented the file system API for attribute directories, and index
directories.
Introduced a new macro FS_MOUNT_CALL() to call fs ops directly from the
mount structure.
get_new_fd() now panics if it is called with an unknown fd type.

e04fced505 The available file systems aren't load anymore on startup.

unloaded in case of an error in vfs_load_fs_module()).

remove_attr(), and rename_attr() is missing for now.

c2f9230c91 For some strange reason, elf_relocate_rel() crashed and reported a high
rel type (111) when it tried to load the PCI bus manager - I've only removed
the crash, but I didn't dig any deeper yet.
Note, this only happens using bochs - on a real computer, the kernel runs
obviously without any problems.

91363a4278 Converted thread states to BeOS equivalents (excluding THREAD_STATE_FREE_ON_RESCHED, which will probably go away once the slab allocator is in). Converted priorities to BeOS equivalents; we now have 60 priority queues to map the 120 BeOS priority levels (which have a granularity of 2, thanks Axel) plus the idle queue. Fixed PS.

ae372703ce Big commit: Added symlink support to the kernel.
- added needed syscalls to access symlink support from userland
- implemented lstat(), symlink(), and readlink()
- added dev_t to ktypes.h (for now - should be in a public header anyway)
- added symlink support to the "ls" command (now calls lstat() and shows the
  link target with the -l option)
- changed the sys_read_stat() call to support symlinks, and updated files
  using that function (it gets an extra argument: bool traverseLink)

7d141659a6 Fixed some crucial bugs in the elf_load_uspace() function:
- if the path name exceeded about 56 bytes, the function would have seg-faulted
- the calculation to decide if there is an extra region for the bss needed was wrong -
  that caused the kernel to be not able to load certain executables

Also, fixed a warning, and cleaned up the above mentioned function a bit, added
some more comments.

3fe5330ccb While Intel documentation lists PCI capability as 32 bit entities,
the PCI specifications lists it as two 8 bit entities, followed by
a unknown number of vendor specific data. It should be better to do
two 8 bit reads, instead of one 16 or 32 bit access.

f3b40ada80 This is a 5 minute attempted fix for Marcus's AGP card not working
for VGA accesses.

Marcus: can you try this and see if it makes any difference? There should
be a debug message if it detects your agp bridge and applies the fix.
