[PATCH V2 0/4] Handle physical address bits

[Jim Fehlig]

Hi All,

This is a V2 of Dario's old patches adding support for specifying the
virtual CPU address size in bits

https://listman.redhat.com/archives/libvir-list/2020-October/210901.html

I've rebased those patches to latest master and tweaked them a bit. E.g.
I removed the qemucaps code since phys-bits and host-phys-bits have been
around before the minimum qemu version supported by libvirt. I also added
patches to expose the number of host address bits and ensure ABI stability
as requested in the old review comments.

Dario Faggioli (2):
  conf: Add support for specifying CPU max physical address size
  qemu: Add support for max physical address size

Jim Fehlig (2):
  capabilities: Report number of host CPU physical address bits
  cpu conf: Check ABI stability of CPU maxphysaddr config
