[Xen-devel] [PATCH] iommu: Fix hvm_dpci_eoi for smp guest in ioapic interrupt mode

[Wei Wang2 <wei.wang2@xxxxxxx>]

Hi,
My testing shows, for some smp guests, ent->fields.mask will not be
unmasked when hvm_dpci_eoi() is invoked at the first time. In that case,
we should rely on timeout call back to do pirq_guest_eoi() and should
not stop the per-irq timer too early.
