Kbuild updates for v5.5
- remove unneeded asm headers from hexagon, ia64 - add 'dir-pkg' target, which works like 'tar-pkg' but skips archiving - add 'helpnewconfig' target, which shows help for new CONFIG options - support 'make nsdeps' for external modules - make rebuilds faster by deleting $(wildcard $^) checks - remove compile tests for kernel-space headers - refactor modpost to simplify modversion handling - make single target builds faster - optimize and clean up scripts/kallsyms.c - refactor various Makefiles and scripts -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEbmPs18K1szRHjPqEPYsBB53g2wYFAl3lKCUVHG1hc2FoaXJv eUBrZXJuZWwub3JnAAoJED2LAQed4NsGu9sP/iTW/RjDxbAsu0aP8jFqzLK/xKB/ NQn/+dD76TjEmjgew9AXszf2rJL+ixKVymGM08FV59Bbguvi8XmAB/QXK21Sjb5j rVl3N97TWNkvXM+QJyly23G2UtbubRSPo3g+e70BZrw3lcmrsK+sAmTOL5KtIrNX 9BHM803JwqsMJyvBwTBBw3UFeeBqb38Qx6gmigfSihuDf6pvjoVDKskpsDno3wX7 rdiXYxAsKQLQ/P2ym/bV/Oqe90RqRtV/2/WCpLshlwHkiM9huflv6GjgCkkbAx5H N3TSptlS7l/2B/XKHgA5ALjHjUlxTGBzLLoevarCd8loKcQXFlgx+vd3nM/WJlHJ x9UpTklDwGP9eUBsa9W980tEyUVsFGMAC8EcTdW6NN2IRtuCOSA5N2FYYt8/SDd0 2b3PhElTJIp4pTWSYN6JZxB1R8n/YBgxLqOJ6N2U6B9CdKFUCHlwGH23QfN89km/ WEMP85bsaab/dnyxbwelkoYYYyPgUHsC13AbpkHdrDxMbAGO+G1PwpHxC6ErF2en wRGrcUxWTfHRykO5aJIQtCB9b1fv73134mTzB5fTYd6GtjepGBSBCO9xb2Iy4sc9 Y+nHVVDUrihvSOpJgqh677PcLDutOZR8fFCoc1ZMDAbBsDvrb0Qsee6oEidj98xc 5kXp9YZh/tdh/tdo =zUaB -----END PGP SIGNATURE----- Merge tag 'kbuild-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: - remove unneeded asm headers from hexagon, ia64 - add 'dir-pkg' target, which works like 'tar-pkg' but skips archiving - add 'helpnewconfig' target, which shows help for new CONFIG options - support 'make nsdeps' for external modules - make rebuilds faster by deleting $(wildcard $^) checks - remove compile tests for kernel-space headers - refactor modpost to simplify modversion handling - make single target builds faster - optimize and clean up scripts/kallsyms.c - refactor various Makefiles and scripts * tag 'kbuild-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (59 commits) MAINTAINERS: update Kbuild/Kconfig maintainer's email address scripts/kallsyms: remove redundant initializers scripts/kallsyms: put check_symbol_range() calls close together scripts/kallsyms: make check_symbol_range() void function scripts/kallsyms: move ignored symbol types to is_ignored_symbol() scripts/kallsyms: move more patterns to the ignored_prefixes array scripts/kallsyms: skip ignored symbols very early scripts/kallsyms: add const qualifiers where possible scripts/kallsyms: make find_token() return (unsigned char *) scripts/kallsyms: replace prefix_underscores_count() with strspn() scripts/kallsyms: add sym_name() to mitigate cast ugliness scripts/kallsyms: remove unneeded length check for prefix matching scripts/kallsyms: remove redundant is_arm_mapping_symbol() scripts/kallsyms: set relative_base more effectively scripts/kallsyms: shrink table before sorting it scripts/kallsyms: fix definitely-lost memory leak scripts/kallsyms: remove unneeded #ifndef ARRAY_SIZE kbuild: make single target builds even faster modpost: respect the previous export when 'exported twice' is warned modpost: do not set ->preloaded for symbols from Module.symvers ...alistair/sunxi64-5.5-dsi

header-test-y specifies headers (`*.h`) in the current directory that

header-test-pattern-y

This works as a weaker version of header-test-y, and accepts wildcard

This specifies all the files that matches to `*.h` in the current
