parisc: Fix KBUILD_IMAGE for self-extracting kernel

2021-12-08T08:04:55+00:00

commit 1d7c29b77725d05faff6754d2f5e7c147aedcf93 upstream. Default KBUILD_IMAGE to $(boot)/bzImage if a self-extracting (CONFIG_PARISC_SELF_EXTRACT=y) kernel is to be built. This fixes the bindeb-pkg make target. Signed-off-by: Helge Deller Cc: # v4.14+ Signed-off-by: Greg Kroah-Hartman

parisc: Fix compile failure when building 64-bit kernel natively

2021-09-01T19:52:02+00:00

Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is a cross build or not") broke 64-bit parisc builds on 32-bit parisc systems. Helge mentioned: - 64-bit parisc userspace is not supported yet [1] - hppa gcc does not support "-m64" flag [2] That means, parisc developers working on a 32-bit parisc machine need to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit parisc kernel. After the offending commit, gcc is used in such a case because both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is unset. A correct way is to introduce ARCH=parisc64 because building the 64-bit parisc kernel on a 32-bit parisc system is not exactly a native build, but rather a semi-cross build.

arch: use cross_compiling to check whether it is a cross build or not

2021-05-05T16:49:13+00:00

'cross_compiling' is defined by the top Makefile and available for arch Makefiles to check whether it is a cross build or not. A good thing is the variable name 'cross_compiling' is self-documenting. This is a simple replacement for m68k, mips, sh, for which $(ARCH) and $(SRCARCH) always match. No functional change is intended for xtensa, either. This is rather a fix for parisc because arch/parisc/Makefile defines UTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefix is not working in Kconfig time.

arch: parisc: Remove CONFIG_OPROFILE support

2021-01-29T04:34:52+00:00

The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove the old oprofile's architecture specific support.

kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables

2020-06-11T11:14:41+00:00

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.

Pull Kbuild updates from Masahiro Yamada: - fix warnings in 'make clean' for ARCH=um, hexagon, h8300, unicore32 - ensure to rebuild all objects when the compiler is upgraded - exclude system headers from dependency tracking and fixdep processing - fix potential bit-size mismatch between the kernel and BPF user-mode helper - add the new syntax 'userprogs' to build user-space programs for the target architecture (the same arch as the kernel) - compile user-space sample code under samples/ for the target arch instead of the host arch - make headers_install fail if a CONFIG option is leaked to user-space - sanitize the output format of scripts/checkstack.pl - handle ARM 'push' instruction in scripts/checkstack.pl - error out before modpost if a module name conflict is found - error out when multiple directories are passed to M= because this feature is broken for a long time - add CONFIG_DEBUG_INFO_COMPRESSED to support compressed debug info - a lot of cleanups of modpost - dump vmlinux symbols out into vmlinux.symvers, and reuse it in the second pass of modpost - do not run the second pass of modpost if nothing in modules is updated - install modules.builtin(.modinfo) by 'make install' as well as by 'make modules_install' because it is useful even when CONFIG_MODULES=n - add new command line variables, GZIP, BZIP2, LZOP, LZMA, LZ4, and XZ to allow users to use alternatives such as pigz, pbzip2, etc. * tag 'kbuild-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (96 commits) kbuild: add variables for compression tools Makefile: install modules.builtin even if CONFIG_MODULES=n mksysmap: Fix the mismatch of '.L' symbols in System.map kbuild: doc: rename LDFLAGS to KBUILD_LDFLAGS modpost: change elf_info->size to size_t modpost: remove is_vmlinux() helper modpost: strip .o from modname before calling new_module() modpost: set have_vmlinux in new_module() modpost: remove mod->skip struct member modpost: add mod->is_vmlinux struct member modpost: remove is_vmlinux() call in check_for_{gpl_usage,unused}() modpost: remove mod->is_dot_o struct member modpost: move -d option in scripts/Makefile.modpost modpost: remove -s option modpost: remove get_next_text() and make {grab,release_}file static modpost: use read_text_file() and get_line() for reading text files modpost: avoid false-positive file open error modpost: fix potential mmap'ed file overrun in get_src_version() modpost: add read_text_file() and get_line() helpers modpost: do not call get_modinfo() for vmlinux(.o) ...

kbuild: add variables for compression tools

2020-06-06T14:42:01+00:00

Allow user to use alternative implementations of compression tools, such as pigz, pbzip2, pxz. For example, multi-threaded tools to speed up the build: $ make GZIP=pigz BZIP2=pbzip2 Variables _GZIP, _BZIP2, _LZOP are used internally because original env vars are reserved by the tools. The use of GZIP in gzip tool is obsolete since 2015. However, alternative implementations (e.g., pigz) still rely on it. BZIP2, BZIP, LZOP vars are not obsolescent. The credit goes to @grsecurity. As a sidenote, for multi-threaded lzma, xz compression one can use: $ export XZ_OPT="--threads=0" Signed-off-by: Denis Efremov Signed-off-by: Masahiro Yamada
