#     powerpc/signal64: Use __get_user() to copy sigset_t
#     
#     Usually sigset_t is exactly 8B which is a "trivial" size and does not
#     warrant using __copy_from_user(). Use __get_user() directly in
#     anticipation of future work to remove the trivial size optimizations
#     from __copy_from_user(). Calling __get_user() also results in a small
#     boost to signal handling throughput here.
