These two patches build on the previous "split out arch-specific" work. The
first adds a PPC64 build, basic CPU support, guest RAM mapping (using hugepages),
flat kernel loading and all required arch-specific definitions & structures.
With patches to date, this should build PPC but not necessarily run much.
Subsequent patches add support to emulate an SPAPR-esque machine.
This patch does not include any code borrowed from outside kvmtool.
The second patch is a small fix for generic virtio code (now that we have a
PPC build) which removes reliance on ioeventfds for PPC, which doesn't provide
them.
Matt Evans (2):
kvm tools: Add initial SPAPR PPC64 architecture support
kvm tools: Make virtio-pci's ioeventfd__add_event() fall back
gracefully if ioeventfds unavailable
