#     x86/uaccess: Avoid barrier_nospec() in 64-bit copy_from_user()
#     
#     The barrier_nospec() in 64-bit copy_from_user() is slow. Instead use
#     pointer masking to force the user pointer to all 1's for an invalid
#     address.
#     
#     The kernel test robot reports a 2.6% improvement in the per_thread_ops
#     benchmark [1].
#     
#     This is a variation on a patch originally by Josh Poimboeuf [2].
