The series fixes the issues exposed by the kvm-unit-tests[1] sprs-migration test. The SDAR, MMCR3 were seen to have some typo/refactoring bugs. The first two patches fix them. The remaining patches take care of save-restoring the guest state elements for DEXCR, HASHKEYR and HASHPKEYR SPRs with PHYP during entry-exit. The KVM_PPC_REG too for them are missing which are added for use by the QEMU.
