Hi Avi,
This is my current patch queue for ppc against master.
It contains an important bug fix which can lead to guest freezes when
using PAPR guests with PR KVM.
Please pull.
Alex

H_CEDE should enable the vcpu's MSR:EE bit. It does on "HV" KVM (it's
burried in the assembly code though) and as far as I can tell, qemu
does it as well.
