| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a file to cache the CamelCase variables found by <commit> to reduce the time it takes to scan the include/ directory. Filename is '.checkpatch-camelcase.<commit>' and it is created only only if a .git directory exists. <commit> is determined by the last non-merge commit id in the include/ path.

| * checkpatch: ignore existing CamelCase uses from include/...Joe Perches2013-07-031-7/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | | dtc: ensure #line directives don't consume data from the next lineGrant Likely2013-06-132-117/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS} could match line-break characters. If the #line directive did not contain the optional flags field at the end, this could cause any integer data on the next line to be consumed as part of the #line directive parsing. This could cause syntax errors (i.e. #line parsing consuming the leading 0 from a hex literal 0x1234, leaving x1234 to be parsed as cell data, which is a syntax error), or invalid compilation results (i.e. simply consuming literal 1234 as part of the #line processing, thus removing it from the cell data). Fix this by replacing {WS} with [ \t] so that it can't match line-breaks. Convert all instances of {WS}, even though the other instances should be irrelevant for any well-formed #line directive. This is done for consistency and ultimate safety.

This creates a further reference to the menu's visibilities and when the expression reduction functions do their work, they may remove or modify expressions that have multiple references, thus causing unpredictable side-effects. The following example Kconfig constructs a case where this causes problems: a menu and a prompt which's visibilities depend on the same symbol. When invoking mconf with this Kconfig and pressing "Z" we see a problem caused by a free'd expression still referenced by the menu's visibility: ------------------------------------------------------------------------ mainmenu "Kconfig Testing Configuration" config VISIBLE def_bool n config Placeholder bool "Place holder" menu "Invisible" visible if VISIBLE config TEST_VAR bool "Test option" if VISIBLE endmenu ------------------------------------------------------------------------ This patch fixes this problem by creating copies of the menu's visibility expressions before AND-ing them with the prompt's one.

* | | kbuild: Don't assume dts files live in arch/*/boot/dtsMatthijs Kooijman2013-05-231-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit b40b25ff (kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp), dts building was changed to always use the C preprocessor. This meant that the .dts file passed to dtc is not the original, but the preprocessed one. When compiling with a separate build directory (i.e., with O=), this preprocessed file will not live in the same directory as the original. When the .dts file includes .dtsi files, dtc will look for them in the build directory, not in the source directory and compilation will fail. The commit referenced above tried to fix this by passing arch/*/boot/dts as an include path to dtc. However, for mips, the .dts files are not in this directory, so dts compilation on mips breaks for some targets. Instead of hardcoding this particular include path, this commit just uses the directory of the .dts file that is being compiled, which effectively restores the previous behaviour wrt includes. For most .dts files, this path is just the same as the previous hardcoded arch/*/boot/dts path. This was tested on a mips (rt3052) and an arm (bcm2835) target.

|/ | | | | | | | | | | Commit 6501320311664e11ad5489fedb17ea1f817c2617 dropped the rpm spec as a prerequisite for the binrpm-pkg target but forgot to update $< usage, which causes the rule to break. This commit fixes that by replacing $< with the spec name. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The *pkg targets are always run, so it makes no sense to cache the generated specfile. This also fixes build errors when the specfile becomes out of date, without the Makefile noticing it: $ make rpm works $ echo yadadada >localversion-test $ make rpm fails, because kernel.spec assumes the old kernel release string Signed-off-by: Michal Marek <mmarek@suse.cz>
| * rpm-pkg: Do not write to the parent directoryMichal Marek2013-04-181-7/+5
| | | | | | | | | | | | | | Now that we only package explicitly listed files to the tarball, there is no need to abuse the parent directory. Signed-off-by: Michal Marek <mmarek@suse.cz>
| * rpm-pkg: Do not package the whole source directoryMichal Marek2013-04-181-1/+5
| | | | | | | | | | | | | | | | | | | | | | The source tree can contain lots of uninteresting data like tag or cscope files, packaging which slows down make rpm needlessly. It can also break the build, if the tree contains an unrelated file named *.spec. The downside of this change is that new subdirectories have to be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The upside is that the behavior is more predictable.

| * buildtar: Add ARCH to the archive nameBorislav Petkov2013-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | When dealing with multiple sub-arches (like 32- and 64-bit on x86, for example) generating a bunch of kernel tar archives with the same name but for different sub-arches could get confusing and error-prone. Also, the build process could overwrite otherwise unrelated builds and you probably don't want that. So, add the architecture to the archive name for more clarity and less shoot-yourself-in-the-foot practices. Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Michal Marek <mmarek@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | The FLAGS variable is factorized independently of the ONLINE mode. The OPTIONS variable is now based on LINUXINCLUDE and explicit includes are thus removed. The format of the -I option differs between gcc and spatch. The COCCIINCLUDE is used to adapt the format. This rewritting needs bash. Signed-off-by: Nicolas Palix <nicolas.palix@imag.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>
