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.
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
