Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha

Pull alpha updates from Al Viro:
 "Mostly small janitorial fixes but there's also more important ones: a
  patch to fix loading large modules from Edward Humes, and some fixes
  from Al Viro"

[ The fixes from Al mostly came in separately through Al's trees too and
  are now duplicated..   - Linus ]
