Kbuild updates for v5.17

- Add new kconfig target 'make mod2noconfig', which will be useful to speed up the build and test iteration. - Raise the minimum supported version of LLVM to 11.0.0 - Refactor certs/Makefile - Change the format of include/config/auto.conf to stop double-quoting string type CONFIG options. - Fix ARCH=sh builds in dash - Separate compression macros for general purposes (cmd_bzip2 etc.) and the ones for decompressors (cmd_bzip2_with_size etc.) - Misc Makefile cleanups -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEbmPs18K1szRHjPqEPYsBB53g2wYFAmHnFNIVHG1hc2FoaXJv eUBrZXJuZWwub3JnAAoJED2LAQed4NsGiQEP/1tkt9IHP7vFvkN9xChQI8HQ7HOC mPIxBAUzHIp1V2IALb0lfojjnpkzcMNpJZVlmqjgyYShLEPPBFwKVXs1War6GViX aprUMz7w1zR/vZJ2fplFmrkNwSxNp3+LSE6sHVmsliS4Vfzh7CjHb8DnaKjBvQLZ M+eQugjHsWI3d3E81/qtRG5EaVs6q8osF3b0Km59mrESWVYKqwlUP3aUyQCCUGFK mI+zC4SrHH6EAIZd//VpaleXxVtDcjjadb7Iru5MFhFdCBIRoSC3d1IWPUNUKNnK i0ocDXuIoAulA/mROgrpyAzLXg10qYMwwTmX+tplkHA055gKcY/v4aHym6ypH+TX 6zd34UMTLM32LSjs8hssiQT8BiZU0uZoa/m2E9IBaiExA2sTsRZxgQMKXFFaPQJl jn4cRiG0K1NDeRKtq4xh2WO46OS4sPlR6zW9EXDEsS/bI05Y7LpUz7Flt6iA2Mq3 0g8uYIYr/9drl96X83tFgTkxxB6lpB29tbsmsrKJRGxvrCDnAhXlXhPCkMajkm2Q PjJfNtMFzwemSZWq09+F+X5BgCjzZtroOdFI9FTMNhGWyaUJZXCtcXQ6UTIKnTHO cDjcURvh+l56eNEQ5SMTNtAkxB+pX8gPUmyO1wLwRUT4YodxylkTUXGyBBR9tgTn Yks1TnPD06ld364l =8BQf -----END PGP SIGNATURE----- Merge tag 'kbuild-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: - Add new kconfig target 'make mod2noconfig', which will be useful to speed up the build and test iteration. - Raise the minimum supported version of LLVM to 11.0.0 - Refactor certs/Makefile - Change the format of include/config/auto.conf to stop double-quoting string type CONFIG options. - Fix ARCH=sh builds in dash - Separate compression macros for general purposes (cmd_bzip2 etc.) and the ones for decompressors (cmd_bzip2_with_size etc.) - Misc Makefile cleanups * tag 'kbuild-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (34 commits) kbuild: add cmd_file_size arch: decompressor: remove useless vmlinux.bin.all-y kbuild: rename cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22} kbuild: drop $(size_append) from cmd_zstd sh: rename suffix-y to suffix_y doc: kbuild: fix default in `imply` table microblaze: use built-in function to get CPU_{MAJOR,MINOR,REV} certs: move scripts/extract-cert to certs/ kbuild: do not quote string values in include/config/auto.conf kbuild: do not include include/config/auto.conf from shell scripts certs: simplify $(srctree)/ handling and remove config_filename macro kbuild: stop using config_filename in scripts/Makefile.modsign certs: remove misleading comments about GCC PR certs: refactor file cleaning certs: remove unneeded -I$(srctree) option for system_certificates.o certs: unify duplicated cmd_extract_certs and improve the log certs: use $< and $@ to simplify the key generation rule kbuild: remove headers_check stub kbuild: move headers_check.pl to usr/include/ certs: use if_changed to re-generate the key when the key type is changed ...

-# When a Kconfig string contains a filename, it is suitable for
-# passing to shell commands. It is surrounded by double-quotes, and
-# any double-quotes or backslashes within it are escaped by
-# backslashes.
-#
-# This is no use for dependencies or $(wildcard). We need to strip the
-# surrounding quotes and the escaping from quotes and backslashes, and
-# we *do* need to escape any spaces in the string. So, for example:
-#
-# Usage: $(eval $(call config_filename,FOO))
-#
-# Defines FOO_FILENAME based on the contents of the CONFIG_FOO option,
-# transformed as described above to be suitable for use within the
-# makefile.
-#
-# Also, if the filename is a relative filename and exists in the source
-# tree but not the build tree, define FOO_SRCPREFIX as $(srctree)/ to
-# be prefixed to *both* command invocation and dependencies.
-#
-# Note: We also print the filenames in the quiet_cmd_foo text, and
-# perhaps ought to have a version specially escaped for that purpose.
-# But it's only cosmetic, and $(patsubst "%",%,$(CONFIG_FOO)) is good
-# enough.  It'll strip the quotes in the common case where there's no
-# space and it's a simple filename, and it'll retain the quotes when
-# there's a space. There are some esoteric cases in which it'll print
-# the wrong thing, but we don't really care. The actual dependencies
-# and commands *do* get it right, with various combinations of single
-# and double quotes, backslashes and spaces in the filenames.
