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()
