Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().
More complete and *almost* functional versions of IA-64 context_save() and context_restore().

Begin support for FPU context switching on platforms which can't do it in lazy way.

Added fpu_context.h arch dep files and removed struct fpu_context from context.h files

Blank line added :-)

Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.
Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().

Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.

Added fpu_context_t type.
IA-32's version of this type contains array of 512 bytes to be used by FXSAVE ... instructions.

Add stdarg.h to support variable argument list functions on architectures with compiler support for __builtin_va_*.
stackarg.h is kept for those architectures which lack that kind of support and for testing purposes.
Make printing functions use the __native type and support the maximum integer width.

Typo corrected.

More ACPI work.
Initial MADT table parsing.
SMP renaming and reorganization to reflect there are more ways to bring SMP up.

ACPI detection code.
MP detection code rewrite.
Minor changes.

Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.

Small improvements.

Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.

Fix wrong order of *_init() function calls.

Smarter definition of CPU macro.

/SPARTAN/trunk/
Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.

Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
