H. Peter Anvin 7263dda41b x86, smap: Handle csum_partial_copy_*_user() ...

Add SMAP annotations to csum_partial_copy_to/from_user().  These
functions legitimately access user space and thus need to set the AC
flag.

TODO: add explicit checks that the side with the kernel space pointer
really points into kernel space.
