Alexey Dobriyan	0e0345b77a	kbuild: redo fake deps at include/config/*.h ... Make include/config/foo/bar.h fake deps files generation simpler. * delete .h suffix those aren't header files, shorten filenames, * delete tolower() Linux filesystems can deal with both upper and lowercase filenames very well, * put everything in 1 directory Presumably 'mkdir -p' split is from dark times when filesystems handled huge directories badly, disks were round adding to seek times. x86_64 allmodconfig lists 12364 files in include/config. ../obj/include/config/ ├── 104_QUAD_8 ├── 60XX_WDT ├── 64BIT ... ├── ZSWAP_DEFAULT_ON ├── ZSWAP_ZPOOL_DEFAULT └── ZSWAP_ZPOOL_DEFAULT_ZBUD 0 directories, 12364 files Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>	2021-04-25 05:26:10 +09:00
Masahiro Yamada	ce6ed1c4c9	kbuild: rebuild GCC plugins when the compiler is upgraded ... Linus reported a build error due to the GCC plugin incompatibility when the compiler is upgraded. [1] GCC plugins are tied to a particular GCC version. So, they must be rebuilt when the compiler is upgraded. This seems to be a long-standing flaw since the initial support of GCC plugins. Extend commit 8b59cd81dc ("kbuild: ensure full rebuild when the compiler is updated"), so that GCC plugins are covered by the compiler upgrade detection.
