Ack. I'm not a fan of the x86-64 usercopy funmctions.
That said, I think you should uninline those things, and move them
from a header file to a C file (arch/x86/lib/uaccess.c?).
Move all the copy_user_generic_unrolled/string garbage there too, and
keep the header file simple.
Because I think that we would actually be better off trying to inline
the copy_user_generic_string() thing into the various versions (in
that uaccess.c file) than try to inline the access_ok() check into the
caller.
