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. |

Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled. |

IA-32 boot Makefile bugfix.
Previous version did not take 512B of boot sector code into account and produced wrong image.bin. |

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. |

IA-64 work.
Add the rest of branch registers to context_t.
Add predicate registers to context_t.
Modify context_save()/context_restore() to save/restore branch registers and predicate registers.
Change SP_DELTA to 0 since both context_save() and context_restore() are leaf procedures and as such don't use the scratch area.
Change pri_t to be __u64 instead of __u32. |

Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.
IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().
Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id(). |

For each architecture, add function/macro FADDR that calculates absolute address of a function referenced by void (* f)(void).
IA-32 and MIPS gcc's use direct addressing (f == FADDR(f)) while IA-64 gcc uses indirect addressing (f != FADDR(f)).
Tweaks in IA-64 Makefile.inc to declare constant gp and main Makefile to consider ASFLAGS when compiling .s targets. |

Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK. |
