In userspace(), mark "eax" as clobbered register.		  
314 6860 d 20 h palkovsky /SPARTAN/trunk/ Small cleanups  
312 6860 d 21 h jermar /SPARTAN/trunk/arch/ia32/ According to IA-32 ABI, %edx and %ecx don't have to be saved accross function calls.
Remove these registers from context_t and adjust context_save() and context_restore() to make use of this fact.		  
311 6860 d 22 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Minor after fixes to madt parsing  
310 6860 d 22 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed possible non-consequentive local apic madt entries
Request for peer review - was not possible to test.		  
309 6861 d 9 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
305 6861 d 21 h jermar /SPARTAN/trunk/ Change processor type in simics.conf to x86-hammer.
This way it supports both IA-32 and AMD64.

Fix comment in i8259.c.		  
302 6862 d 4 h palkovsky /SPARTAN/trunk/arch/ia32/src/drivers/ Fixed bad slave i8259 initialization.  
300 6862 d 7 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6862 d 7 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6862 d 10 h jermar /SPARTAN/trunk/arch/ Add timeout to kmp() so that we don't deadlock while waiting for AP's to come up.

Improve comment in byteorder.h.		  
291 6862 d 23 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ AP cpus are not supposed to touch A20 for this bit is enabled by the BSP cpu.  
285 6863 d 9 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
282 6863 d 11 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.		  
281 6863 d 19 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
280 6863 d 19 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6863 d 21 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
278 6863 d 22 h palkovsky /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed ACPI to work correctly even in bochs.  
277 6863 d 22 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
