"Finishing the conversion of readdir.c to unsafe_... API.
This includes the uaccess_{read,write}_begin series by Christophe
Leroy"
* 'uaccess.readdir' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
readdir.c: get rid of the last __put_user(), drop now-useless access_ok()
readdir.c: get compat_filldir() more or less in sync with filldir()
switch readdir(2) to unsafe_copy_dirent_name()
drm/i915/gem: Replace user_access_begin by user_write_access_begin
uaccess: Selectively open read or write user access
uaccess: Add user_read_access_begin/end and user_write_access_begin/end
