#     x86/uaccess: utilize CONFIG_CC_HAS_ASM_GOTO_OUTPUT
#     
#     Clang-11 shipped support for outputs to asm goto statments along the
#     fallthrough path.  Double up some of the get_user() and related macros
#     to be able to take advantage of this extended GNU C extension. This
#     should help improve the generated code's performance for these accesses.
