282 6866 d 22 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.		  
277 6867 d 9 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!		  
275 6867 d 10 h palkovsky /SPARTAN/trunk/arch/ Moved AMD64 kernel above 1MB.  
273 6867 d 12 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
268 6867 d 13 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
266 6867 d 16 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
265 6867 d 17 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).

Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.		  
252 6867 d 23 h palkovsky /SPARTAN/trunk/arch/amd64/ Added volatile to inb/outb, so that it does not optimeze
lot of things out anymore.
Working delay loop.		  
251 6868 d 6 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.

231 6869 d 15 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better coding style  
230 6869 d 15 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
