Bug description:
The following set of patches are needed for SR-IOV on larger VM sizes
on Hyper-V, especially with more than 32 CPUs. Some of these patches
were already pulled in as SAUCE for SR-IOV in Azure previously.

next.git/commit/?id=22e2495b76dbe398540faf355a541b10faad33b9
Merge branch 'pci/host-hv' into next
* pci/host-hv:
PCI: hv: Allocate interrupt descriptors with GFP_ATOMIC
PCI: hv: Specify CPU_AFFINITY_ALL for MSI affinity when >= 32 CPUs
PCI: hv: Lock PCI bus on device eject
PCI: hv: Properly handle PCI bus remove
