* 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.
