Merge git://git.infradead.org/~dwmw2/khdrs-2.6

* git://git.infradead.org/~dwmw2/khdrs-2.6:
  New 'make headers_install_all' target.
  Use dependencies for 'make headers_install'.
  [S390] Unexport <asm/z90crypt.h>, export <asm/zcrypt.h> in its place.
  Remove dead netfilter_logging.h from include/linux/Kbuild
  Remove offsetof() from user-visible <linux/stddef.h>
  Clean up exported headers on CRIS
  Fix v850 exported headers
  Don't advertise (or allow) headers_{install,check} where inappropriate.
  Remove UML header export
  Remove ARM26 header export.
  Fix H8300 exported headers.
  Fix m68knommu exported headers
  Fix exported headers for SPARC, SPARC64
  Fix 'make headers_check' on m32r
  Fix 'make headers_check' on sh64
  Fix 'make headers_check' on sh
  [HEADERS] Fix ARM 'make headers_check'

Initial pass of manual conflict resolution in top-level Makefile over
conflicting build rule and headers_install changes.
