copy_user_page() is needed by DAX. Without this we get a compile error
for DAX on SH:
fs/dax.c:280:2: error: implicit declaration of function ‘copy_user_page’
[-Werror=implicit-function-declaration]
copy_user_page(vto, (void __force *)vfrom, vaddr, to);
^
This was done with a random config that happened to include DAX support.
This patch has only been compile tested.
