MSR TS bits can be modified with non-privileged instruction such as tbegin./tend. That means guest can change MSR value "silently" without notifying host. It is necessary to sync the TM bits to host so that host can calculate shadow msr correctly. Note, privileged mode in the guest will always fail transactions so we only take care of problem state mode in the guest. The logic is put into kvmppc_copy_from_svcpu() so that kvmppc_handle_exit_pr() can use correct MSR TM bits even when preemption occurs. Signed-off-by:
