Patches #1 and #2 are just cleanup: some exported headers were still under a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was not under an uapi directory. After these three patches, all exported headers are under an uapi directory: path #4 stops searching files in non uapi directories. The patch #5 was spotted by code review: there is no in-tree user of this functionality. Patch #6 fixes some warnings/errors reported by 0-day tests. Patch #7 to #9 fix some errors when the corresponding files are included by userland. Patches #10 and #11 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. Michal, is this series going through your tree? v7 -> v8: - rebase on top of linus tree - add patch #7, #8 and #9 v6 -> v7: - rebase on top of linus tree - patch #7: remove autogenerated files from the list in the commit log v5 -> v6: - patch #6: remove change of include/uapi/linux/media.h - patch #7: fix hdr export when 'make O=' is used (look for genhdr files in the right directory) - patch #8: fix 'make headers_check' v4 -> v5: - patch #3: get back to v3 (don't export msr-index.h) - patch #6: new in this version - patch #7: fix compilation by introducing header-n v3 -> v4: - first patch has been included - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h 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
