2010-10-14ftrace: Rename config option HAVE_C_MCOUNT_RECORD to HAVE_C_RECORDMCOUNTSteven Rostedt
The config option used by archs to let the build system know that the C version of the recordmcount works for said arch is currently called HAVE_C_MCOUNT_RECORD which enables BUILD_C_RECORDMCOUNT. 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.

2010-10-14ftrace/x86: Add support for C version of recordmcountSteven Rostedt
This patch adds the support for the C version of recordmcount and compile times show ~ 12% improvement. After verifying this works, other archs can add: HAVE_C_MCOUNT_RECORD in its Kconfig and it will use the C version of recordmcount instead of the perl version.

2010-09-22jump label: Base patch for jump labelJason Baron
base patch to implement 'jump labeling'. Based on a new 'asm goto' inline assembly gcc mechanism, we can now branch to labels from an 'asm goto' statment. This allows us to create a 'no-op' fastpath, which can subsequently be patched with a jump to the slowpath code. This is useful for code which might be rarely used, but which we'd like to be able to call, if needed. Tracepoints are the current usecase that these are being implemented for. Acked-by: David S.

2010-09-02ARM: 6312/1: ftrace: allow building without frame pointersRabin Vincent
With current gcc, compiling with both -pg and -fomit-frame-pointer is not allowed. 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.

It is now possible to assign options to AS and CC on the command line - which is only used for built-in code. {A,C}FLAGS_KERNEL was used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC without overriding the original value.

2010-07-14Kbuild: Add option to set -femit-struct-debug-baseonlyAndi Kleen
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.

2010-06-18kbuild: Clean up and speed up the localversion logicMichal Marek
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.

2010-06-15kbuild: fix LOCALVERSION handling to match descriptionAndy Whitcroft
In the commit below the version string handling was modified, adding a '+' where no other version information was supplied: commit 85a256d8e0116c8f5ad276730830f5d4d473344d Author: David Rientjes <> Date: Wed Jan 13 13:01:05 2010 -0800 From the commit the intent was as below: - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the repository has been revised beyond a tagged commit and LOCALVERSION= was not passed to "make". However if the user supplies an empty LOCALVERSION on the command line the plus suffix is still added. This form is useful in the case where the build environment knows that the version as specified is correct and complete but does not correspond to a specific tag. This patch changes the implementation to match the documentation such that specifying LOCALVERSION= on the build line is sufficient to suppress any suffix.

2010-06-12Add a target to use the Coccinelle checkerNicolas Palix
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.
