Merge branch 'uaccess.csum' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull uaccess/csum updates from Al Viro:
"Regularize the sitation with uaccess checksum primitives:
- fold csum_partial_... into csum_and_copy_..._user()
- on x86 collapse several access_ok()/stac()/clac() into
user_access_begin()/user_access_end()"
* 'uaccess.csum' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
default csum_and_copy_to_user(): don't bother with access_ok()
take the dummy csum_and_copy_from_user() into net/checksum.h
arm: switch to csum_and_copy_from_user()
sh32: convert to csum_and_copy_from_user()
m68k: convert to csum_and_copy_from_user()
xtensa: switch to providing csum_and_copy_from_user()
sparc: switch to providing csum_and_copy_from_user()
parisc: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
alpha: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
ia64: turn csum_partial_copy_from_user() into csum_and_copy_from_user()
ia64: csum_partial_copy_nocheck(): don't abuse csum_partial_copy_from_user()
x86: switch 32bit csum_and_copy_to_user() to user_access_{begin,end}()
x86: switch both 32bit and 64bit to providing csum_and_copy_from_user()
x86_64: csum_..._copy_..._user(): switch to unsafe_..._user()
get rid of csum_partial_copy_to_user()
