Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

Pull more tile architecture updates from Chris Metcalf:
 "This second batch of changes is just cleanup of various kinds from
  doing some tidying work in the sources.

  Some dead code is removed, comment typos fixed, whitespace and style
  issues cleaned up, and some header updates from our internal
  "upstream" architecture team"

* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  tile: remove stray blank space
  tile: <arch/> header updates from upstream
  tile: improve gxio iorpc autogenerated code style
  tile: double default VMALLOC space
  tile: remove stale arch/tile/kernel/futex_64.S
  tile: remove HUGE_VMAP dead code
  tile: use pmd_pfn() instead of casting via pte_t
  tile: fix typos in comment in arch/tile/kernel/unaligned.c
