Merge tag 'kbuild-v4.21-3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada: - improve boolinit.cocci and use_after_iter.cocci semantic patches - fix alignment for kallsyms - move 'asm goto' compiler test to Kconfig and clean up jump_label CONFIG option - generate asm-generic wrappers automatically if arch does not implement mandatory UAPI headers - remove redundant generic-y defines - misc cleanups * tag 'kbuild-v4.21-3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: kconfig: rename generated .*conf-cfg to *conf-cfg kbuild: remove unnecessary stubs for archheader and archscripts kbuild: use assignment instead of define ... endef for filechk_* rules arch: remove redundant UAPI generic-y defines kbuild: generate asm-generic wrappers if mandatory headers are missing arch: remove stale comments "UAPI Header export list" riscv: remove redundant kernel-space generic-y kbuild: change filechk to surround the given command with { } kbuild: remove redundant target cleaning on failure kbuild: clean up rule_dtc_dt_yaml kbuild: remove UIMAGE_IN and UIMAGE_OUT jump_label: move 'asm goto' support test to Kconfig kallsyms: lower alignment on ARM scripts: coccinelle: boolinit: drop warnings on named constants scripts: coccinelle: check for redeclaration kconfig: remove unused "file" field of yylval union nds32: remove redundant kernel-space generic-y nios2: remove unneeded HAS_DMA define
