* | fbdev: work around old compiler bugStephen Rothwell2009-06-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with a 4.1.x compiler on powerpc64 (at least) we get this error: drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict This was introduced by commit ae52bb2384f721562f15f719de1acb8e934733cb ("fbdev: move logo externs to header file"). This is a partial revert of that commit sufficient to not hit the compiler bug. Also convert _clut arrays from __initconst to __initdata. Sam said: Al analysed this some time ago. When we say something is const then _sometimes_ gcc annotate the section as const(?) - sometimes not. So if we have two variables/functions annotated __*const and gcc decides to annotate the section const only in one case we get a section type conflict.

* gcov: add gcov profiling infrastructurePeter Oberparleiter2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

This patch adds a very simple helper script gfp-translate for the mode: portion of the page allocation failure messages. An example usage looks like mel@machina:~/linux-2.6 $ scripts/gfp-translate 0x4020 Source: /home/mel/linux-2.6 Parsing: 0x4020 #define __GFP_HIGH (0x20) /* Should access emergency pools? */ #define __GFP_COMP (0x4000) /* Add compound page metadata */ The script is not a work of art but it has come in handy for me a few times so I thought I would share.

The patch is slightly more complicated than I'd hoped because unifdef needs to see lines fully evaluated - doing otherwise causes it to mark the line as "dirty" and copy it over no matter what.

| * scripts/headers_check.pl: correct RE in header CONFIG leak checkRobert P. J. Day2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct the regular expression in scripts/headers_check.pl to include '_' as a valid character in the class; otherwise, the check will report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A. This patch will make no difference whatsoever in the current kernel tree as the call to the perl routine that does that check is currently commented out: &check_include(); &check_asm_types(); &check_sizetypes(); &check_prototypes(); # Dropped for now. Too much noise &check_config(); However, I noticed that problem when I was building the yum downloadable kernel source rpm for fedora 11 (beta), which *does* run that check, and that's where the problem became obvious.

| * kconfig: do not hardcode "include/config/auto.conf" filenameMarkus Heidelberg2009-06-09
| | | | | | | | | | | | | | | | | | | | | | Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target into "include/config/auto.conf.cmd" was always the default one. Of course this doesn't make it work for the Kernel kbuild system, since there the filename is hardcoded at several places in the Makefiles.

| * kconfig: do not hardcode ".config" filenameMarkus Heidelberg2009-06-09
| | | | | | | | | | | | | | | | | | | | | | Rather than hardcoding ".config" use conf_get_configname(), which also respects the environment variable KCONFIG_CONFIG. This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also suggests the given filename for "Load" and "Save as" in qconf.
