Log:
Shuffle the APIC interrupt vectors around a bit:
- Move the IPI and local APIC interrupt vectors up into the 0xf0 - 0xff
range. The pmap lazyfix IPI was reordered down next to the TLB
shootdowns to avoid conflicting with the spurious interrupt vector.
- Move the base of APIC interrupts up 16 so that the first 16 APIC
interrupts do not overlap the vectors used by the ATPIC.
- Remove bogus interrupt vector reservations for LINT[01].
- Now that 0xc0 - 0xef are available, use them for device interrupts.
This increases the number of APIC device interrupts to 191.
- Increase the system-wide number of global interrupts to 191 to catch up
to more APIC interrupts.
