#     powerpc/uaccess: Use asm goto for get_user when compiler supports it
#     
#     clang 11 and future GCC are supporting asm goto with outputs.
#     
#     Use it to implement get_user in order to get better generated code.
#     
#     Note that clang requires to set x in the default branch of
#     __get_user_size_goto() otherwise is compliant about x not being
#     initialised :puzzled:
