#     powerpc/book3s64/pkeys: Optimize FTR_KUAP and FTR_KUEP disabled case
#     
#     If FTR_KUAP is disabled kernel will continue to run with the same AMR
#     value with which it was entered. Hence there is a high chance that
#     we can return without restoring the AMR value. This also helps the case
#     when applications are not using the pkey feature. In this case, different
#     applications will have the same AMR values and hence we can avoid restoring
#     AMR in this case too.
#     
#     Also avoid isync() if not really needed.
#     
#     Do the same for IAMR.
