| * kbuild/recordmcount: Add RECORDMCOUNT_WARN to warn about mcount callersSteven Rostedt2011-05-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When mcount is called in a section that ftrace will not modify it into a nop, we want to warn about this. But not warn about this always. Now if the user builds the kernel with the option RECORDMCOUNT_WARN=1 then the build will warn about mcount callers that are ignored and will just waste execution time.

| * KBuild: silence "'scripts/unifdef' is up to date."Mike Waychison2011-03-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While changing our build system over to use the headers_install target as part of our klibc build, the following message started showing up in our logs: make[2]: `scripts/unifdef' is up to date. It turns out that the build blindly invokes a recursive make on this target, which causes make to emit this message when the target is already up to date. This isn't seen for most targets as the rest of the build relies primarily on the default target and on PHONY targets when invoking make recursively. Silence the above message when building unifdef as part of headers_install by hiding it behind a new PHONY target called "build_unifdef" that has an empty recipe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a 'W=1' Makefile switch which adds additional checking per build object. The idea behind this option is targeted at developers who, in the process of writing their code, want to do the occasional make W=1 [target.o] and let gcc do more extensive code checking for them. Then, they could eyeball the output for valid gcc warnings about various bugs/discrepancies which are not reported during the normal build process.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you try to build a kernel with KCONFIG_CONFIG set (to a value not equal to .config) and that config sets CONFIG_IKCONFIG then the build will fail with: make[1]: *** No rule to make target `.config', needed by \ `kernel/config_data.gz'. Stop. because the kernel/Makefile contains a direct reference to .config. This issue has been present since the introduction of KCONFIG_CONFIG in 14cdd3c402bf7c66f0bcd76e290f0770a54a4b21.

However, -pg can be used to build without actually specifying -fno-omit-frame-pointer, upon which the default behaviour for the target will be used. On ARM, it is not possible to build a Thumb-2 kernel with -fno-omit-frame-pointer (FRAME_POINTERS depends on !THUMB2_KERNEL). In order to support ftrace for Thumb-2, we need to be able to allow a combination of FUNCTION_TRACER and !FRAME_POINTER. We do this by omitting -fomit-frame-pointer if ftrace is enabled.

To be more consistent with the name that all archs may use, it has been renamed to HAVE_C_RECORDMCOUNT. This will be less confusing since we are building a C recordmcount and not a mcount_record.
