[PATCH 0/3] Fix pci-hyperv interrupt code on a nested root partition

From: Wei Liu <[email protected]>

There are two issues in pci-hyperv when Linux runs as the root partition
on a nested setup.

1. Interrupt state between Linux and the hypervisor is out of sync due
   to pci-hyperv not issuing unmap hypercall.
2. Interrupt migration is broken due to Linux doesn't retarget
   interrupts correctly.

The first patch is trivial. The two issues are fixed by two separate
patches.
