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.
