7c0a93573b Preparation for MTRR support, code is completely untested, though.
The CPU specific MTRR code will be in modules.

7b7c38a2a7 The "where" or "sc" command now switches the page directory to the specified thread
to be able to follow the stack trace into userland.
No symbols there, yet, though.

90ce9e8305 Added calls to read and write the MSR, the machine state register.
Minor cleanup.

8e26b085e5 Fixed double fault handler. Personally I disclaim all responsiblity
for these changes. I was mostly just staring in amazement at the screen
while Axel and Thomas were discussing IA32 internals. A particularly
fascinating moment was when Thomas produced the cause of a bug we had
been trying to track down for hours off the top of his head (of course
iret behaves specially when the NT bit is set :-). His slowness must be
excused though, since he hadn't slept for more then 30 hours. ;-)

The code doesn't wholeheartedly deal with multi-processor machines yet.
Axel will certainly do some cleanup...

edb5566393 Fixed struct tss; there is no ss3/sp3.
Moved ptentry/pdentry to arch_vm_translation_map.c and renamed them to
page_table_entry and page_directory_entry.
Fixed a race condition that happened when memory was remapped (which
can currently happen because lock_memory() does not work correctly, and
there might be other conditions as well, like certain vm_store fault
handlers). Now, page table and directory entries are updated atomically.

* Made the parameter for restoring the FPU state const.

afad65ded7 Replaced all remaining PAGE_SIZE with B_PAGE_SIZE, addr with addr_t.
Removed the definition of PAGE_SIZE and addr.

75df143732 Introduced a macro specifying the type function parameters are aligned to. Not nice, but seems to help with the automatic generation of syscall code (at least on x86).

a02a5888af Added another argument parameter for the thread creation code. Helps
implementing a more efficient on_exit_thread().

074a16b53e Added a private tls.h file with definitions for the reserved TLS slots.
Renamed i386_set_kstack() to i386_set_tss_and_kstack(), because that's what
it does.
Added a new function arch_thread_init_tls() which must be called after
having allocated the TLS area.
Renamed arch_thread_initialize_kthread_stack() to arch_thread_init_kthread_stack()
to be more consistent.
Changed the parameters for arch_thread_enter_uspace() - it now gets a pointer
to the thread structure and takes the user stack pointer from there (which
might also be architectural different).

7208e95f0e Moved the gdt_idt_descr struct from arch_stage2.h to stage2_priv.h.
Moved the tss_descriptor structure to descriptor.h, updated it to be a
segment_descriptor structure, and provided inlines for set_tss_descriptor(),
set_segment_descriptor(), set_segment_descriptor_base(), and
clear_segment_descriptor().
Also added defines for the different privilege levels and descriptor types.
Removed the unusused and incorrect TSS definition, introduced new
TSS_BASE_SEGMENT and TLS_BASE_SEGMENT macros.
Removed include of arch/cpu.h in arch_cpu.h.

5ca8da7a4b Backported the new stack crawl command ("sc", not "bt" like in NewOS) from
NewOS. Untested yet, though.

fde77afb37 Ported my NewOS changes to OpenBeOS.
A couple of changes in various interrupt and thread functions and structures.
These make it now possible to change the stack at any time without making the kernel crash. This is needed for calling VESA 3.0 VBE functions through the protected mode interface.
