    Assign IRQs to HPET Timers
"
in x86.git

cause my servers hang
after
Calling initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100()

after reverting that I got:

initcall 0xffffffff80b947d1 ran for 19 msecs: pci_iommu_init+0x0/0x13()
Calling initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100()
hpet0: at MMIO 0xfed00000, IRQs 2, 8, 31
hpet0: 3 32-bit timers, 25000000 Hz
initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100() returned 0.
initcall 0xffffffff80b9a465 ran for 7 msecs: hpet_late_init+0x0/0x100()

           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
      CPU6       CPU7
  0:         86          0          0          0          0          0
         1          0   IO-APIC-edge      timer
  4:          0          0          0          0          0          0
         1        838   IO-APIC-edge      serial
  7:          1          0          0          0          0          0
         0          0   IO-APIC-edge
  8:          0          0          0          0          0          0
         0          0   IO-APIC-edge      rtc0

for mcp55, it should already route hpet to ioapic pin2 or the irq0.
