* 'header-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (50 commits) x86: headers cleanup - setup.h emu101k1.h: fix duplicate include of <linux/types.h> compiler-gcc4: conditionalize #error on __KERNEL__ remove __KERNEL_STRICT_NAMES make netfilter use strict integer types make drm headers use strict integer types make MTD headers use strict integer types make most exported headers use strict integer types make exported headers use strict posix types unconditionally include asm/types.h from linux/types.h make linux/types.h as assembly safe Neither asm/types.h nor linux/types.h is required for arch/ia64/include/asm/fpu.h headers_check fix cleanup: linux/reiserfs_fs.h headers_check fix cleanup: linux/nubus.h headers_check fix cleanup: linux/coda_psdev.h headers_check fix: x86, setup.h headers_check fix: x86, prctl.h headers_check fix: linux/reinserfs_fs.h headers_check fix: linux/socket.h headers_check fix: linux/nubus.h ...
