Subject: [PATCH 04/37] KVM: ppc: split out common Book E instruction emulation
From: Hollis Blanchard <hollisb@...ibm.com>
The Book E code will be shared with e500.
I've left PID in kvmppc_core_emulate_op() just so that we don't need to move
kvmppc_set_pid() right now. Once we have the e500 implementation, we can
probably share that too.
