I'm taking this patch, but with the following commit log:

  Due to the way kbuild works, this header was unintentionally exported
  back in 2013 when it was created, despite it not being in a uapi/
  directory.  This is very non-intuitive behaviour by Kbuild.

  However, we've had this include exported to userland for almost four
  years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
  no hint that anyone has complained about it.  So, let's make it
  officially exported in this state.

If anyone has any objections, they better shout sooner rather than
later.
