* 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.
