[PATCH 0/5 v4] Read guest last instruction from kvmppc_get_last_inst()

Read guest last instruction from kvmppc_get_last_inst() allowing the function
to fail in order to emulate again. On bookehv architecture search for
the physical address and kmap it, instead of using Load External PID (lwepx)
instruction. This fixes an infinite loop caused by lwepx's data TLB miss
exception handled in the host and the TODO for execute-but-not-read entries
and TLB eviction.

  KVM: PPC: Book3s: Remove kvmppc_read_inst() function
  KVM: PPC: Alow kvmppc_get_last_inst() to fail
  KVM: PPC: Bookehv: Get vcpu's last instruction for emulation
