Hi,
This is version 3 of a series of patches that I originally posted in:

Changes since version 2:
- The vmstate related to 'driftfix' is now in a separate subsection
that can be migrated conditionally.
- The new fields of the HPETTimer structure are no longer initialized
in hpet_init(). This is now done in hpet_reset() only.
- Compensation of lost timer interrupts is now based on a backlog of
unaccounted HPET clock periods instead of 'irqs_to_inject'. This
eliminates the need to scale 'irqs_to_inject' when a guest o/s
modifies the comparator register value.
Please review and please comment.
Regards,
Uli
