[git pull] vfs.git uaccess.h preparations

[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
(i.e
    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.

	One really trivial conflict in arch/x86/mm/fault.c update of
comment in my branch vs. update of include in mainline.  Typo in the
comment still needs fixing, despite the switch from module.h to
extable.h...
