Merge branch 'set_fs-4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic into asm-generic
Christoph Hellwig and a few others spent a huge effort on removing set_fs() from most of the important architectures, but about half the other architectures were never completed even though most of them don't actually use set_fs() at all. I did a patch for microblaze at some point, which turned out to be fairly generic, and now ported it to most other architectures, using new generic implementations of access_ok() and __{get,put}_kernel_nocheck(). Three architectures (sparc64, ia64, and sh) needed some extra work, which I also completed. * 'set_fs-4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: uaccess: remove CONFIG_SET_FS ia64: remove CONFIG_SET_FS support sh: remove CONFIG_SET_FS support sparc64: remove CONFIG_SET_FS support lib/test_lockup: fix kernel pointer check for separate address spaces uaccess: generalize access_ok() uaccess: fix type mismatch warnings from access_ok() arm64: simplify access_ok() m68k: fix access_ok for coldfire MIPS: use simpler access_ok() MIPS: Handle address errors for accesses above CPU max virtual user address uaccess: add generic __{get,put}_kernel_nofault nios2: drop access_ok() check from __put_user() x86: use more conventional access_ok() definition x86: remove __range_not_ok() sparc64: add __{get,put}_kernel_nofault() nds32: fix access_ok() checks in get/put_user uaccess: fix nios2 and microblaze get_user_8() uaccess: fix integer overflow on access_ok()
