Subject: [PATCH v2 0/3] PCI: hv: Generify pci-hyperv.c

Hi,

This is the first part for virtual PCI support of Hyper-V guest on
ARM64. The whole patchset doesn't have any functional change, but only
refactors the pci-hyperv.c code to make it more arch-independent.

Previous version:
v1: https://lore.kernel.org/lkml/20200121015713.69691-1-boqun.feng@gmail.com/

Changes since v1:

*	Reword the commit log and adjust the title as per Bjorn's
	suggestion

*	Split patch #2 into two patches (one for moving and one for
	adding new structure) as per Bjorn's suggestion

*	Remove unnecesarry #if guard as per Vitaly's suggestion.

*	Add explanation for adding hv_set_msi_address_from_desc().

I've done compile and boot test of this patchset, also done some tests
with a pass-through NVMe device.

Suggestions and comments are welcome!

Regards,
Boqun
