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.
changes in v2:
- Moved the irqchip implementation to drivers/pci as suggested
by Marc Zyngier
- Addressed Multi-MSI handling issues identified by Marc Zyngier
- Addressed lock/synchronization primitive as suggested by Marc
Zyngier
- Addressed other code feedback from Marc Zyngier

If you have occasion to post a v3, note that this is not correctly
threaded with patches as responses to the cover letter. Thereore,

Yes, thanks for the heads up. Appears to me that Outlook doesn't work well with
patch series. I will setup the 'git send-email' and make sure that v3 is threaded
properly.
