Here is the v3 of this series. The first 5 patches are just cleanup: some exported headers were still under a non-uapi directory or (x86 case) were wrongly exported. The patch 6 was spotted by code review: there is no in-tree user of this functionality. Patches 7 and 8 remove the need to list explicitly headers. Now all files under an uapi directory are exported. This series has been tested with a 'make headers_install' on x86 and a 'make headers_install_all'. I've checked the result of both commands. This patch is built against linus tree. If I must rebase it against the kbuild tree, just tell me ;-) v2 -> v3: - patch #1: remove arch/arm/include/asm/types.h - patch #2: remove arch/h8300/include/asm/bitsperlong.h - patch #3: remove arch/nios2/include/uapi/asm/setup.h - patch #4: don't export msr-index.h - patch #5: fix a typo: s/unput-files3-name/input-files3-name - patch #6: no change - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y - add patch #8 v1 -> v2: - add patch #1 to #6 - patch #7: remove use of header-y Comments are welcomed, Nicolas
