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. |

IA-64 work.
Add application registers ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_t.
Add store/load operations for ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_save()/restore().
Add application registers ar.rcs, ar.bsp and ar.rnat to context_t.
Proper store/load operations for ar.rcs, ar.bsp and ar.rnat is in the works.
FPU cleanup.
Remove call set_TS_flag() from cpu_identify().
Remove unneeded includes from FPU test #1. |

FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.
Re-enable O3 again.
Revert Makefile.config not to compile in any tests. |

IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.
Build script for IA-32 changed to build floppy images (image.bin) 1440K long. |

it runs first time OK. |
