* git://git.infradead.org/hdrinstall-2.6: Remove export of include/linux/isdn/tpam.h Remove <linux/i2c-id.h> and <linux/i2c-algo-ite.h> from userspace export Restrict headers exported to userspace for SPARC and SPARC64 Add empty Kbuild files for 'make headers_install' in remaining arches. Add Kbuild file for Alpha 'make headers_install' Add Kbuild file for SPARC 'make headers_install' Add Kbuild file for IA64 'make headers_install' Add Kbuild file for S390 'make headers_install' Add Kbuild file for i386 'make headers_install' Add Kbuild file for x86_64 'make headers_install' Add Kbuild file for PowerPC 'make headers_install' Add generic Kbuild files for 'make headers_install' Basic implementation of 'make headers_check' Basic implementation of 'make headers_install'
