Kbuild core: - remove unneeded $(call cc-option,...) switches - consolidate Clang compiler flags into CLANG_FLAGS - announce the deprecation of SUBDIRS - fix single target build for external module - simplify the dependencies of 'prepare' stage targets - allow fixdep to directly write to .*.cmd files - simplify dependency generation for CONFIG_TRIM_UNUSED_KSYMS - change if_changed_rule to accept multi-line recipe - move .SECONDARY special target to scripts/Kbuild.include - remove redundant 'set -e' - improve parallel execution for CONFIG_HEADERS_CHECK - misc cleanups Treewide fixes and cleanups - set Clang flags correctly for PowerPC boot images - fix UML build error with CONFIG_GCC_PLUGINS - remove unneeded patterns from .gitignore files - refactor firmware/Makefile - remove unneeded rules for *offsets.s - avoid unneeded regeneration of intermediate .s files - clean up ./Kbuild Modpost: - remove unused -M, -K options - fix false positive warnings about section mismatch - use simple devtable lookup instead of linker magic - misc cleanups Coccinelle: - relax boolinit.cocci checks for overall consistency - fix warning messages of boolinit.cocci Other tools: - improve -dirty check of scripts/setlocalversion - add a tool to generate compile_commands.json from .*.cmd files -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJcJiVeAAoJED2LAQed4NsGXEMP/1fdkBfZGxYlxp4w1tEBeRKZ GInxxMfHiHZlu7nFPQ3k1mncczZjeLbnKcLaybnPmqBSfQe1F7tN0ux1sHtWkVfI DvqoKaHObZ3lEMEVxCHXQ2bKrN/j9nB2xSxzr4dvc9DscW8dwKElZuKVE7nHKdhl z70xsalxHGEGY6hptJrucbv8KTBOSleZ8Gaat79sEDkDSLCTjxXB3WcVMWqDT0M/ IqN5QCwiPjZC3UCwuqq6+vnG1gyvDUORcbrVgHrBIKxLYAABYzugB5IlLpi8B31C ZUDmijSTandHd4SG5gw5uZoyYuK4YhZeI7g4yNyXSqnPurmcJxrGdpiuwRcE7xet 5yB2uaNbAFO6Fbz4gUdDEvryA9IZEPPn1Z0Btfpp7UOxiWEqE61oHReCNdkiad94 Oonl+ROZw5UOT3AZD3xCZTf9bTnQoCFccHTmnbaKqqSiDWxxLUXum7sNfnJ6GXEb fNQDuwuxtsPStaWoU93QNrGyl5e8jYTKFdphUCnZZ2/hE8ygoQ06PYmeBAk+UKfN UI2IqR8PHgmA97XJg+fHhbw6X4nQcPsg/usLqxGItAZNO2O4uXgaN24dOcHG74Bu 2Dk/gQQB2sVB/Dxfmlaxvvj98MVg7IMtpusAT2bQ7miiSS3EqPFT8KQMZYLICWuZ u7QQe20yCho3ZULmsRwH =0PCt -----END PGP SIGNATURE----- Merge tag 'kbuild-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: "Kbuild core: - remove unneeded $(call cc-option,...) switches - consolidate Clang compiler flags into CLANG_FLAGS - announce the deprecation of SUBDIRS - fix single target build for external module - simplify the dependencies of 'prepare' stage targets - allow fixdep to directly write to .*.cmd files - simplify dependency generation for CONFIG_TRIM_UNUSED_KSYMS - change if_changed_rule to accept multi-line recipe - move .SECONDARY special target to scripts/Kbuild.include - remove redundant 'set -e' - improve parallel execution for CONFIG_HEADERS_CHECK - misc cleanups Treewide fixes and cleanups - set Clang flags correctly for PowerPC boot images - fix UML build error with CONFIG_GCC_PLUGINS - remove unneeded patterns from .gitignore files - refactor firmware/Makefile - remove unneeded rules for *offsets.s - avoid unneeded regeneration of intermediate .s files - clean up ./Kbuild Modpost: - remove unused -M, -K options - fix false positive warnings about section mismatch - use simple devtable lookup instead of linker magic - misc cleanups Coccinelle: - relax boolinit.cocci checks for overall consistency - fix warning messages of boolinit.cocci Other tools: - improve -dirty check of scripts/setlocalversion - add a tool to generate compile_commands.json from .*.cmd files" * tag 'kbuild-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (51 commits) kbuild: remove unused cmd_gentimeconst kbuild: remove $(obj)/ prefixes in ./Kbuild treewide: add intermediate .s files to targets treewide: remove explicit rules for *offsets.s firmware: refactor firmware/Makefile firmware: remove unnecessary patterns from .gitignore scripts: remove unnecessary ihex2fw and check-lc_ctypes from .gitignore um: remove unused filechk_gen_header in Makefile scripts: add a tool to produce a compile_commands.json file kbuild: add -Werror=implicit-int flag unconditionally kbuild: add -Werror=strict-prototypes flag unconditionally kbuild: add -fno-PIE flag unconditionally scripts: coccinelle: Correct warning message scripts: coccinelle: only suggest true/false in files that already use them kbuild: handle part-of-module correctly for *.ll and *.symtypes kbuild: refactor part-of-module kbuild: refactor quiet_modtag kbuild: remove redundant quiet_modtag for $(obj-m) kbuild: refactor Makefile.asm-generic user/Makefile: Fix typo and capitalization in comment section ...
