#     powerpc/64s/kuap: Restore AMR in fast_interrupt_return
#     
#     Interrupts that use fast_interrupt_return actually do lock AMR, but
#     they have been ones which tend to come from userspace (or kernel bugs)
#     in radix mode. With kuap on hash, segment interrupts are taken in
#     kernel often, which quickly breaks due to the missing restore.
