[PATCH] x86/hvm: fix corrupt ACPI PM-Timer during live migration
The value of ACPI PM-Timer may be broken on save unless the timer mode
is delay_for_missed_ticks.
With other timer modes, vcpu->arch.hvm_vcpu.guest_time is always zero
and the adjustment from its value is wrong.
This patch fixes the saved value of ACPI PM-Timer:
- don''t adjust the PM-Timer if vcpu->arch.hvm_vcpu.guest_time is zero.
- consolidate calculations of PM-Timer to one
