It is enabled by defining FPU_LAZY		  
305 6853 d 12 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 6853 d 19 h palkovsky /SPARTAN/trunk/arch/ia32/src/drivers/ Fixed bad slave i8259 initialization.  
300 6853 d 21 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6853 d 22 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
294 6854 d 1 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.

285 6855 d 0 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
282 6855 d 2 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 6855 d 10 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
280 6855 d 10 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6855 d 12 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
278 6855 d 13 h palkovsky /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed ACPI to work correctly even in bochs.

269 6855 d 17 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6855 d 17 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6855 d 18 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken
