46 6959 d 22 h vana /SPARTAN/trunk/ 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.		  
45 6960 d 2 h vana /SPARTAN/trunk/ Added fpu_context_t type.
IA-32's version of this type contains array of 512 bytes to be used by FXSAVE ... instructions.		  
42 6960 d 15 h jermar /SPARTAN/trunk/ 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.		  
41 6961 d 23 h jermar /SPARTAN/trunk/include/ Typo corrected.  
40 6961 d 23 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
34 6967 d 19 h jermar /SPARTAN/trunk/ More ACPI work.
Initial MADT table parsing.

SMP renaming and reorganization to reflect there are more ways to bring SMP up.		  
32 6970 d 15 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
31 6971 d 20 h jermar /SPARTAN/trunk/ 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.		  
28 6973 d 0 h jermar /SPARTAN/trunk/ Small improvements.  
26 6975 d 22 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
23 6978 d 20 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
22 6980 d 18 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
20 6984 d 22 h jermar /SPARTAN/trunk/ Smarter definition of CPU macro.  
16 6987 d 20 h jermar /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.		  
15 6988 d 18 h jermar /SPARTAN/trunk/ 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.		  
10 7032 d 0 h jermar /SPARTAN/trunk/ Be more careful when sending IPI on UP configured as SMP.  
9 7034 d 0 h jermar /SPARTAN/trunk/include/smp/ Forgot to add this in revision 7.  
7 7034 d 0 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
6 7035 d 4 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7035 d 14 h jermar /SPARTAN/trunk/ TLB shootdown.
