KVM: PPC: PV mtmsrd L=1 The PowerPC ISA has a special instruction for mtmsr that only changes the EE and RI bits, namely the L=1 form. Since that one is reasonably often occuring and simple to implement, let's go with this first. Writing EE=0 is always just a store. Doing EE=1 also requires us to check for pending interrupts and if necessary exit back to the hypervisor. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
