2010-06-12Add a target to use the Coccinelle checkerNicolas Palix4-3/+74
A 'coccicheck' target is added. It can be called with four different modes. Each one generates a different kind of output, i.e. context, patch, org, report, according to the corresponding mode to be activated. The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.

2010-05-06kbuild: Fix checking of scm-identifier variableGreg Thelen1-1/+1
I'm looking Makefile in the -mm branch (dated 2010-04-28-16-53) and seeing what looks like a bug in the checking of scm-identifier. The "ifneq ($scm-identifier)" seems to always execute "ifeq ($(LOCALVERSION,)) ...". This patch fixes the checking of scm-identifier.

2010-04-14gconfig: add support to show hidden options that have promptsLi Zefan2-11/+64
There's a button in gconfig to "Show all options", but I think normally we are not interested in those configs which have no prompt and thus can't be changed, so here I add a new button to show hidden options which have prompts.

2010-04-14menuconfig: add support to show hidden options which have promptsLi Zefan4-16/+41
Usage: Press <Z> to show all config symbols which have prompts. Quote Tim Bird: | I've been bitten by this numerous times. I most often | use ftrace on ARM, but when I go back to x86, I almost | always go through a sequence of searching for the | function graph tracer in the menus, then realizing it's | completely missing until I disable CC_OPTIMIZE_FOR_SIZE. | | Is there any way to have the menu item appear, but be | unsettable unless the SIZE option is disabled? I'm | not a Kconfig guru... I myself found this useful too. For example, I need to test ftrace/tracing and want to be sure all the tracing features are enabled, so I enter the "Tracers" menu, and press <Z> to see if there is any config hidden. I also noticed gconfig and xconfig have a button "Show all options", but that's a bit too much, and I think normally what we are not interested in those configs which have no prompt thus can't be changed by users. Exmaple: --- Tracers -*- Kernel Function Tracer - - Kernel Function Graph Tracer [*] Interrupts-off Latency Tracer - - Preemption-off Latency Tracer [*] Sysprof Tracer Here you can see 2 tracers are not selectable, and then can find out how to make them selectable.

2010-03-23kconfig: recalc symbol value before showing search resultsLi Zefan1-0/+1
A symbol's value won't be recalc-ed until we save config file or enter the menu where the symbol sits. So If I enable OPTIMIZE_FOR_SIZE, and search FUNCTION_GRAPH_TRACER: Symbol: FUNCTION_GRAPH_TRACER [=y] Prompt: Kernel Function Graph Tracer Defined at kernel/trace/Kconfig:140 Depends on: ... [=y] && (!X86_32 [=y] || !CC_OPTIMIZE_FOR_SIZE [=y]) ... From the dependency it should result in FUNCTION_GRAPH_TRACER=n, but it still shows FUNCTION_GRAPH_TRACER=y.

2010-03-23headerdep: perlcritic warningStephen Hemminger1-2/+1
Minor perlcritic warning: headerdep.pl: "return" statement with explicit "undef" at line 84, column 2. See page 199 of PBP. (Severity: 5) The rationale according to PBP is that an explicit return of undef (contrary to most people's expectations) doesn't always evaluate as false. It has to with the fact that perl return value depends on context the function is called. If function is used in list context, the appropriate return value for false is an empty list; whereas in scalar context the return value for false is undefined. By just using a "return" both cases are handled. In the context of a trivial script this doesn't matter. But one script may be cut-paste into later code (most people like me only know 50% of perl), that is why perlcritic always complains Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
