2014-07-18kbuild: allow to override Python command nameMasahiro Yamada1-1/+2
The specification of Python 3 is largely different from that of Python 2. For example, arch/ia64/scripts/unwcheck.py seems to be written in Python 2, not compatible with Python 3. It is not a good idea to invoke python scripts with the hard-coded command name 'python'. The command 'python' could possibly be Python 3 on some systems. For that case, it is reasonable to allow to override the command name by giving 'PYTHON=python2' from the command line. The 'python' in arch/ia64/Makefile should be replaced with '$(PYTHON)'.

2014-07-04kbuild: Do not print the build directory with make -sMichal Marek1-47/+50
Commit c2e28dc9 (kbuild: Print the name of the build directory) prints the name of the build directory for O= builds, but we should not be doing this in make -s mode, so that commands like make -s O=<dir> kernelrelease can be used by scripts.

2014-06-09Makefile: Fix unrecognized cross-compiler command line optionsGeert Uytterhoeven1-4/+6
On architectures that setup CROSS_COMPILE in their arch/*/Makefile (arc, blackfin, m68k, mips, parisc, score, sh, tile, unicore32, xtensa), cc-option and cc-disable-warning may check against the wrong compiler, causing errors like cc1: error: unrecognized command line option "-Wno-maybe-uninitialized" if the host gcc supports a compiler option, while the cross compiler doesn't support that option. Move all logic using cc-option or cc-disable-warning below the inclusion of the arch's Makefile to fix this. Introduced by - commit e74fc973b6e531fef1fce8b101ffff05ecfb774c ("Turn off -Wmaybe-uninitialized when building with -Os"), - commit 61163efae02040f66a95c8ed17f4407951ba58fa ("kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang"). As -Wno-maybe-uninitialized requires a quite recent gcc (gcc 4.6.3 on Ubuntu 12.04 LTS doesn't support it), this only showed up recently (gcc 4.8.2 on Ubuntu 14.04 LTS does support it).

2014-05-14kbuild: Use relative path when building in a subdir of the source treeMichal Marek1-1/+11
When doing make O=<subdir>, use '..' to refer to the source tree. This allows for more readable compiler messages, and, more importantly, it sets the VPATH to '..', so filenames in WARN_ON() etc. will be shorter. Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
2014-05-14kbuild: Use relative path when building in the source treeMichal Marek1-2/+2
When not using O=, $(srctree) refers to the same directory as $(objtree), so we can set it to '.' as well. This makes the default include path more compact and results in more readable messages from the compiler. The only case where we need the absolute path is when creating the 'source' symlink in /lib/modules. Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

2014-04-30kbuild: support simultaneous "make %config" and "make all"Masahiro Yamada1-2/+10
Kbuild is supposed to support mixed targets. (%config and build targets) But "make all" did nothing if it was run with configuration targets. For example, $ LANG=C make defconfig all HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf *** Default configuration is based on 'x86_64_defconfig' # # configuration written to .config # make: Nothing to be done for `all'.

W=... provides extra gcc checks. Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories. Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.

2014-04-08scripts: objdiff: detect object code changes between two commitsJason Cooper1-1/+1
objdiff is useful when doing large code cleanups. For example, when removing checkpatch warnings and errors from new drivers in the staging tree. objdiff can be used in conjunction with a git rebase to confirm that each commit made no changes to the resulting object code. It has the same return values as diff(1). This was written specifically to support adding the skein and threefish cryto drivers to the staging tree. I needed a programmatic way to confirm that commits changing >90% of the lines didn't inadvertently change the code. Temporary files (objdump output) are stored in /path/to/linux/.tmp_objdiff 'make mrproper' will remove this directory.

2014-03-29kbuild: unconditionally clobber include/linux/version.h on distcleanPaul Gortmaker1-1/+1
As of v3.7, the UAPI changes relocated headers around such that the kernel version header lived in a new place. If a person is bisecting and if you go back to pre-UAPI days, you will create an include/linux/version.h -- then if you checkout a post-UAPI kernel, and even run "make distclean" it still won't delete that old version file. So you get a situation like this: $ grep -R LINUX_VERSION_CODE include/ include/generated/uapi/linux/version.h:#define LINUX_VERSION_CODE 200192 include/linux/version.h:#define LINUX_VERSION_CODE 132646 The value in that second line is representative of a v2.6.38 version. And it will be sourced/used, hence leading to strange behaviours, such as drivers/staging content (which typically hasn't been purged of version ifdefs) failing to build. Since it is a subtle mode of failure, lets always clobber the old file when doing a distclean.
