I applied these with Long's reviewed-by to pci/host-hv for v4.12 with the
following subject lines:

  PCI: hv: Specify CPU_AFFINITY_ALL for MSI affinity when >= 32 CPUs
  PCI: hv: Allocate interrupt descriptors with GFP_ATOMIC

There were two copies of [1/2], which makes this error-prone.  I applied
the second one that defines CPU_AFFINITY_ALL.

They're both marked for stable, but without any clue about when the
problems were introduced or how serious they are, I did not queue them for
v4.11.  If you want them in v4.11, please supply those additional details.
