[Hyper-V] PCI passthrough fixes for 32 or more CPUs

[Joshua R. Poulson]

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.

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-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

These should all apply to 4.4, 4.8, and 4.10

I built X, Y and Z test kernels with the requested commits. The test kernels can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1682665/

Xenial only needed the second two commits. The first two were already included as SAUCE patches.

Can you test this kernel and see if it resolves this bug?

Thanks in advance!
