  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.
