KVM: PPC: Book3E: Refactor ONE_REG ioctl implementation
Refactor Book3E ONE_REG ioctl implementation to use kvmppc_get_one_reg/ kvmppc_set_one_reg delegation interface introduced by Book3S. This is necessary for MMU SPRs which are platform specifics. Get rid of useless case braces in the process. Signed-off-by: Mihai Caraman <mihai.caraman@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
