[Xen-devel] [Patch] Fix x64 SMP Vista's Bug Check 0x101 issue

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

x64 SMP Vista HVM guest uses HPET as the main system timer, and it uses
physical destination mode with broadcast to deliver the interrupts
generated by HPET. In current code, timer interrupts are injected only
to VCPU0 in vioapic.c, but this doesn't satisfy x64 SMP Vista -- when it
boots, it complains "a clock interrupt was not received on a secondary
processor within the allocated time interval" with Bug Check 0x101.
The attached patch fixes the issue.
