Paul Mackerras a5ddea0e78 KVM: PPC: Book3S HV: Save and restore CR in __kvmppc_vcore_entry 
The ABI specifies that CR fields CR2--CR4 are nonvolatile across function
calls.  Currently __kvmppc_vcore_entry doesn't save and restore the CR,
leading to CR2--CR4 getting corrupted with guest values, possibly leading
to incorrect behaviour in its caller.  This adds instructions to save
and restore CR at the points where we save and restore the nonvolatile
GPRs.
