KVM: PPC: Book3S PR: Pass through MSR TM and TS bits to shadow_msr
PowerPC TM functionality needs MSR TM/TS bits support in hardware level. Guest TM functionality can not be emulated with "fake" MSR (msr in magic page) TS bits. This patch syncs TM/TS bits in shadow_msr with the MSR value in magic page, so that the MSR TS value which guest sees is consistent with actual MSR bits running in guest.
