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.

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.

All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

* | | | Kbuild: Add option to set -femit-struct-debug-baseonlyAndi Kleen2010-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This patch fixes it, 'make kernelrelease' will show the same version name with the one you finally get.

* | | kbuild: Clean up and speed up the localversion logicMichal Marek2010-06-18
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | kbuild: Fix checking of scm-identifier variableGreg Thelen2010-05-06
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | kbuild: move -fno-dwarf2-cfi-asm to powerpc onlyAndi Kleen2010-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Better dwarf2 unwind information is a good thing, it allows better debugging with kgdb and crash and helps systemtap. Commit 003086497f07f7f1e67c0c295e261740f822b377 ("Build with -fno-dwarf2-cfi-asm") disabled some CFI information globally to work around a module loader bug on powerpc. But this disables the better unwind tables for all architectures, not just powerpc. Move the workaround to powerpc and also add a suitable comment that's it really a workaround. This improves dwarf2 unwind tables on x86 at least.

* | kbuild: improve version string logicDavid Rientjes2010-02-02

This allows users to uniquely identify their kernel builds with a string. If CONFIG_LOCALVERSION_AUTO is enabled, the unique SCM tag reported by setlocalversion (or .scmversion) is appended to the kernel version, if it exists. When CONFIG_LOCALVERSION_AUTO is not enabled, a `+' is appended to the kernel version to represent that the kernel has been revised since the last release unless "make LOCALVERSION=" was used to uniquely identify the build. The end result is this: - when LOCALVERSION= is passed to "make", it is appended to the kernel version, - when CONFIG_LOCALVERSION_AUTO is enabled, a unique SCM identifier is appended if the respository has been revised beyond a tagged commit, and - 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". Examples: With CONFIG_LOCALVERSION_AUTO: "make" results in v2.6.32-rc4-00149-ga3ccf63. If there are uncommited changes to the respository, it results in v2.6.32-rc4-00149-ga3ccf63-dirty. If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild-00149-ga3ccf63-dirty. Without CONFIG_LOCALVERSION_AUTO, "make" results in v2.6.32-rc4+ unless the repository is at the Linux v2.6.32-rc4 commit (in which case the version would be v2.6.32-rc4). If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild. Also renames variables such as localver-auto and _localver-auto to more accurately describe what they represent: localver-extra and scm-identifier, respectively.
