[PATCH 0/2] PCI: hv: Hyper-V vPCI for ARM64

[Sunil Muthuswamy]

Current Hyper-V vPCI code only compiles and works for x64. There are
some hardcoded assumptions about the architectural IRQ chip and other
arch defines.

This patch series adds support for Hyper-V vPCI for ARM64 by first
breaking the current hard coded dependency in the vPCI code and
making it arch neutral. That is in the first patch. The second
patch introduces a Hyper-V vPCI MSI IRQ chip for allocating SPI
vectors.

This patch depends on two other independent patch sets. First one
is the patch series from Michael Kelley titled:
"Enable Linux guests on Hyper-V on ARM64"
and the second one is from Boqun Feng titled:
"PCI: hv: Support host bridge probing on ARM64". Neither of these
patches are merged into one branch at the moment. I think its best
to carry this patch with the 'hyperv-next' tree after merging Boqun's
patch series.
