[VTD][RESEND]add a timer for the shared interrupt issue for vt-d
...your comments last time and make some
other small fix:
1) We don''t touch the locking around the hvm_dpci_eoi().
2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse
others.
3) Add some explanation to the return value for the
hvm_pci_intx_assert(), and the has_timer parameter for the hvm_dpci_eoi.
We have tested it with shared interrupt between dom0/HVM(pcie/disk) and
HVM/HVM(pcie/pcie).

[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.
