Merge branch 'work.uaccess2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull uaccess.h prepwork from Al Viro: "Preparations to tree-wide switch to use of linux/uaccess.h (which, obviously, will allow to start unifying stuff for real). The last step there, ie PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>' sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \ `git grep -l "$PATT"|grep -v ^include/linux/uaccess.h` is not taken here - I would prefer to do it once just before or just after -rc1. However, everything should be ready for it" * 'work.uaccess2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: remove a stray reference to asm/uaccess.h in docs sparc64: separate extable_64.h, switch elf_64.h to it score: separate extable.h, switch module.h to it mips: separate extable.h, switch module.h to it x86: separate extable.h, switch sections.h to it remove stray include of asm/uaccess.h from cacheflush.h mn10300: remove a bogus processor.h->uaccess.h include xtensa: split uaccess.h into C and asm sides bonding: quit messing with IOCTL kill __kernel_ds_p off mn10300: finish verify_area() off frv: move HAVE_ARCH_UNMAPPED_AREA to pgtable.h exceptions: detritus removal
