2013-09-11checkpatch: add test for positional misuse of section specifiers like __initdataJoe Perches
As discussed recently on the arm [1] and lm-sensors [2] lists, it is possible to use section markers on variables in a way which gcc doesn't understand (or at least not the way the developer intended): static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = { does NOT put exynos4_plls in the .initdata section. The __initdata marker can be virtually anywhere on the line, EXCEPT right after "struct". The preferred location is before the "=" sign if there is one, or before the trailing ";" otherwise. [1] http://permalink.gmane.org/gmane.linux.ports.arm.kernel/258149 [2] http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039836.html So, update checkpatch to find these misuses and report an error when it's immediately after struct or union, and a warning when it's otherwise not immediately before the ; or =.

2013-09-11checkpatch: reduce runtime/cpu time usedJoe Perches
There are some cases where checkpatch can take a long time to complete. Reduce the likelihood of this long run-time by adding a new test for lines with and without comments and eliminating checks on lines with only comments. This reduces the number of "ctx_statement_block" calls, and also the number of tests of $stat, which is now undefined for these blank lines. One test in particular, the "check for switch/default statements without a break", could take an extremely long time to parse as it tries to skip interleaving comments within the ctx_statement_block/$stat and that could be done multiple times unnecessarily. A small test case taken from cfg80211.h before this patch would take 1000's of seconds to run, now it's just a couple seconds.

2013-09-11checkpatch: enforce sane perl versionDave Hansen
I got a bug report from a couple of users who said checkpatch.pl was broken for them. It was erroring out on fairly random lines most commonly with messages like: Nested quantifiers in regex; marked by <--HERE in m/(\((?:[^\(\)]++ <-- HERE |(?-1))*\))/ at ./checkpatch.pl line 340. The bug reporter was running a version of perl 5.8 which was end-of-lifed in 2008: http://www.cpan.org/src/. Versions of perl this old are at _best_ quite untested. At worst, they are crusty and known to be completely broken. If folks have a system _that_ old, then we should have mercy on them and give them a half-decent error message rather than fail with nutty error messages. This patch enforces that checkpatch.pl is run with perl 5.10, which was end-of-lifed in 2009. The new --ignore-perl-version command-line switch will let folks override this if they want.

2013-09-11checkpatch: check CamelCase by word, not by $LvalJoe Perches
$Lval is a test for complete name (ie: foo->bar.Baz[1]) If any of this is CamelCase, then the current test uses the entire $Lval. This isn't optimal because it can emit messages with foo->bar.Baz and bar.Baz when Baz is a variable specified in an include file. So instead, break the $Lval into words and check each word for CamelCase uses.

2013-09-05kconfig: do not allow more than one symbol to have 'option modules'Yann E. MORIN
Previously, it was possible to have more than one symbol with the 'option modules' attached to them, although only the last one would in fact control tristates. Since this does not make much sense, only allow at most one symbol to control tristates. Note: it is still possible to have more than one symbol that control tristates, but indirectly: config MOD1 bool "mod1" select MODULES config MOD2 bool "mod2" select MODULES config MODULES bool option modules Signed-off-by: "Yann E.

2013-09-05kconfig: do not special-case 'MODULES' symbolYann E. MORIN
Currently, the 'MODULES' symbol is hard-coded to be the default symbol that enables/disables tristates, if no other symbol was declared with 'option modules'. While this used to be needed for the Linux kernel, we now have an explicit 'option modules' attached to the 'MODULES' symbol (since cset 11097a036), so we no longer need to special-case it in the kconfig code. Furthermore, kconfig is extensively used out of the Linux kernel, and other projects may have another meaning for a symbol named 'MODULES'. This patch changes the way we enable/disable tristates: if a symbol was found with 'option modules' attached to it, then that symbol controls enabling tristates. Otherwise, tristates are disabled, even if a symbol named 'MODULES' exists. Signed-off-by: "Yann E.

2013-08-15kconfig: silence warning when parsing auto.conf when a symbol has changed typeYann E. MORIN
When a symbol changes type from tristate to bool, and was previously set to 'm', a subsequent silentoldconfig would warn about inconsistency, such as: include/config/auto.conf:3014:warning: symbol value 'm' invalid for HOTPLUG_PCI_PCIE Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal): git checkout 1fe0135 make mrproper make allmodconfig make silentoldconfig git checkout aa8032b make allmodconfig make silentoldconfig Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig, but then was set to 'y' by the second allmodconfig. Then the second silentoldconfig prints the warning. The warning in this case is a spurious warning, which happens at the time kconfig tries to detect symbols that have changed, to touch the empty header files in include/config used for dependency-tracking by make. Silence the warning when we read the old auto.conf file, since it is perfectly legit that a symbol changed type since the previous call.

2013-07-09checkpatch: make the CamelCase cache work for non-git trees tooJoe Perches
Might as well check include timestamps and cache the include file CamelCase uses for the non-git case too. The camelcase cache file is now named: for git: .checkpatch-camelcase.git.<commit_id> for non-git: .checkpatch-camelcase.date.<YYYYMMDDhhmm> All .checkpatch-camelcase* files are deleted if not current.
