Newer gcc has a -femit-struct-debug-baseonly option that dramatically reduces the size of object files with debug info. What it does is to only emit type information for structures when the structures are defined in the same file or in a header file. This means the type information for most headers are not included. This is not good when the type information is actually needed (e.g. with kgdb or systemtap) But often kernel hackers only care about line numbers and don't need all the type information anyways. In this case setting the option can be a big win: A build dir for a specific x86-64 configuration with gcc 4.5 shrunk from 2.3G to 1.2G. The compilation was also nearly a minute faster.

Now that we run scripts/setlocalversion during every build, it makes sense to move all the localversion logic there. This cleans up the toplevel Makefile and also makes sure that the script is called only once in 'make prepare' (previously, it would be called every time due to a variable expansion in an ifneq statement). No user-visible change is intended, unless one runs the setlocalversion script directly. Reported-by:

commit 37a8d9f6 tried to combine some duplicate code and accidentally broke how KBUILD_SYMTYPES worked This fixes the code to match the original intention by the author who originally added the code I believe. The fixes include: - removing extra whitespaces in the if-statements - moving the if-statement from around the -r to the -T - adding a second arg to cmd_gensymtypes to simplify the options passed to genksyms. Tested by instrumenting genksyms and seeing what options were passed in during a make, KBUILD_SYMTYPES make, and when a foo.symref was created. Everything compiled and looked ok. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by: -

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:
