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. |

Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.
Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch(). |

Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory. |
