[VTD][PATCH] a time out mechanism for the shared interrupt issue for vtd
Attached is a patch for shared interrupt between dom0 and HVM domain for
vtd.
Most of problem is caused by that we should inject interrupt to both
domains and the
physical interrupt deassertion then may be delayed by the device
assigned to the HVM.
The patch adds a timer, and the time out value is sufficient large to
tolerant
the delaying used to wait for the physical interrupt deassertion.

[VTD][patch 0/5] HVM device assignment using vt-d
The following 5 patches are re-submissions of the vt-d patch.
This set of patches has been tested against cs# 15080 and is
now much more mature and tested against more environments than
the original patch. Specifically, we have successfully tested
the patch with following environements:
- 32/64-bit Linux HVM guest
- 32-bit Windows XP/Vista (64-bit should work but did not test)

cpuidle and un-eoid interrupts at the local apic
Recently our automated testing system has caught a curious assertion
while testing Xen 4.1.5 on a HaswellDT system.
