    Merge branch 'work.uaccess' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs · 5db6db0d
    Linus Torvalds authored
    Pull uaccess unification updates from Al Viro:
     "This is the uaccess unification pile. It's _not_ the end of uaccess
      work, but the next batch of that will go into the next cycle. This one
      mostly takes copy_from_user() and friends out of arch/* and gets the
      zero-padding behaviour in sync for all architectures.
    
      Dealing with the nocache/writethrough mess is for the next cycle;
      fortunately, that's x86-only. Same for cleanups in iov_iter.c (I am
      sold on access_ok() in there, BTW; just not in this pile), same for
      reducing __copy_... callsites, strn*... stuff, etc. - there will be a
      pile about as large as this one in the next merge window.
    
      This one sat in -next for weeks. -3KLoC"
