[kvm-ppc-devel] [PATCH 0 of 2] [v2] Fix guest eating 100% cpu when guest is idle on PowerPC

[Jerone Y. <jy...@us...>]

* This update consolidates patches, adds more explicit comments, and add wait check when rfi instruction is emulated.

This set of patches fixes 100% CPU usage when a guest is idle on PowerPC. Idle CPU usage is now at ~15-16% CPU time. An improvment.
