Pull misc UAPI fixes from David Howells:
 "They do a number of things:

  (1) Import a patch from Catalin Marinas to extend the generic-y in
      Kbuild facility to uapi directories.

  (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
      line from the kernel internal side of things.

  (3) Remove some now-empty conditional bits from include/linux/Kbuild.
      The contents got moved to the UAPI side of things along with new
      conditionals.

  (4) Deal with now-empty files:

     (a) Empty Kbuild files under include/ get removed.

     (b) Empty Kbuild files under arch/ get comments to hold them as
         they are likely to end up with generic-y or genhdr-y lines.
         Deleting them appears to work if we want to go that route.

     (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
         patch program from deleting that, and made the arches with
         empty kvm_para.h uapi files use that instead of having their
         own files.

     (d) Put comments into four other empty uapi/ headers to prevent the
         patch program from deleting them.

  A question: Is this the right way to deal with the now-empty Kbuild
  files?

  The ones under include/ are unlikely to be used - even for generated
  files, I think - so getting rid of them is probably okay.  Once all
  the bits are in, we can probably remove all the Kbuild files under
  include/ that aren't also under include/uapi/.

  The ones under arch/ are more of an issue because of the potential for
  generic-y and genhdr-y."
