Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY |

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. |

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

Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code. |

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. |
