hpet: Fix emulation of HPET_TN_SETVAL (Jan Kiszka)
While Intel's spec is not that clear here, latest changes to Linux' HPET code (commit c23e253e67c9d8a91a0ffa33c1f571a17f0a2403, "x86: hpet: stop HPET_COUNTER when programming periodic mode") strongly suggest that HPET_TN_SETVAL rather means: Set _both_ the comparator value and register. With this patch applied, I'm again able to boot 2.6.30-rc kernels as they no longer panic like this (which was due to the comparator register remaining 0): ENABLING IO-APIC IRQs ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... ..... (found apic 0 pin 2) ... ....... failed. ...trying to set up timer as Virtual Wire IRQ... ..... failed. ...trying to set up timer as ExtINT IRQ... ..... failed :(. Kernel panic - not syncing: IO-APIC + timer doesn't work!
