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 <rientjes@google.com> 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.

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.

2010-02-05kbuild: move -fno-dwarf2-cfi-asm to powerpc onlyAndi Kleen
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.

2010-02-02kbuild: improve version string logicDavid Rientjes
The LOCALVERSION= string passed to "make" will now always be appended to the kernel version after CONFIG_LOCALVERSION, if it exists, regardless of whether CONFIG_LOCALVERSION_AUTO is set or not. 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.

2010-02-02kconfig CROSS_COMPILE optionRoland McGrath
This adds CROSS_COMPILE as a kconfig string so you can store it in .config. Then you can use plain "make" in the configured kernel build directory to do the right cross compilation without setting the command-line or environment variable every time. With this, you can set up different build directories for different kernel configurations, whether native or cross-builds, and then use the simple: make -C /build/dir M=module-source-dir idiom to build modules for any given target kernel, indicating which one by nothing but the build directory chosen. I tried a version that defaults the string with env="CROSS_COMPILE" so that in a "make oldconfig" with CROSS_COMPILE in the environment you can just hit return to store the way you're building it. But the kconfig prompt for strings doesn't give you any way to say you want an empty string instead of the default, so I punted that.

2010-01-13Makefile: do not override LC_CTYPEMichal Marek
Setting LC_CTYPE=C breaks localized messages in some setups. With only LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not so defined character classes and tolower()/toupper(). The former is not a big issue, because we can assume that e.g. [:alpha:] will always include a-zA-Z and we only ever process ASCII input. The latter seems only affect arch/sh/tools/gen-mach-types, which we can handle separately. So after this patch the meaning of ranges like [a-z], the behavior of sort and join, etc. should be the same everywhere and at the same time gcc should be able to print localized waring and error messages. LC_NUMERIC=C might not be necessary, but setting it doesn't hurt. Reported-by: Simon Horman <horms@verge.net.au> Reported-by: Sergei Trofimovich <slyfox@inbox.ru> Acked-by: H.

To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules.
