This can reduce almost 3 times the size of the linux-image package, while keeping the debug symbols available for this particular build, in their own package.

2013-07-03checkpatch: ignore existing CamelCase uses from include/...Joe Perches
When using --strict, CamelCase uses are described with CHECK: messages. These CamelCase uses may be acceptable and should not generate these messages when the variable is already defined in a file from the include/... path. So, change checkpatch to read all the .h files in include/... and look for preexisting CamelCase #defines, typedefs and function prototypes. Add these to the existing camelcase hash so that any uses in the patch or file can be ignored. There are currently ~3500 files in include/. It takes about 10 cpu seconds on my little netbook to grep for and preseed these existing uses. That's about 4x the time for a similar git grep. This preseeding is only done once when using --strict and only when there is a CamelCase use found. If a .git directory is found, it uses 'git ls-files include' If not, it uses 'find $root/include -name "*.h" Signed-off-by: Joe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-07-03checkpatch: change CamelCase test and make it --strictJoe Perches
Do not bleat a message on nominally acceptable CamelCase uses that are separated by an _ like drm_core_has_MTRR. CamelCase tests are also a bit noisy against certain types of code acceptable to some kernel developers. Make the test applicable only with --strict.

2013-07-03kbuild: create directory for dir/file.o张忠山
When add a obj with dir to obj-y, like this obj-y += dir/file.o The $(obj)/dir not created, this patch fix this. When try to add a file(which in a subdir) to my board's obj-y, the build progress crashed. For example, I use at91rm9200ek board, and in kernel dir run: mkdir objtree make O=objtree at91rm9200_defconfig mkdir arch/arm/mach-at91/dir touch arch/arm/mach-at91/dir/file.c and edit arch/arm/mach-at91/dir/file.c to add some code. then edit arch/arm/mach-at91/Makefile, change the following line: obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o to: obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o dir/file.o Now build it: make O=objtree Then the error appears: ... CC arch/arm/mach-at91/board-rm9200dk.o CC arch/arm/mach-at91/board-rm9200ek.o CC arch/arm/mach-at91/dir/file.o linux-2.6/arch/arm/mach-at91/dir/file.c:5: fatal error: opening dependency file arch/arm/mach-at91/dir/.file.o.d: No such file or directory Check the objtree: LANG=en ls objtree/arch/arm/mach-at91/dir ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory It's apparently that the target dir not created for file.o Check kbuild source code. It seems that kbuild create dirs for that in $(obj-dirs). But if the dir need not to create a built-in.o, It should never in $(obj-dirs). So I make this patch to make sure It in $(obj-dirs) this bug caused by commit f5fb976520a53f45f8bbf2e851f16b3b5558d485 Signed-off-by: 张忠山 <zzs0213@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
