[HAL] Start implementing APIC support, which is needed for both SMP and x64. It will use the local APIC + I/O APIC for interrupt control, the RTC instead of the PIT for the timer interrupt (PIT doesn't always work with I/O APIC), the APIC timer for profiling and finally the TSC for the performance counter and KeStallExecutionProcessor. The code is incomplete and doesn't work yet svn path=/trunk/; revision=53611 2011-09-06 21:01:49 +00:00
