      kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line · 80c00ba9
      Sam Ravnborg authored
      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.
      
      Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL
      that is used by arch specific files and free up
      {A,C}FLAGS_KERNEL so they can be assigned on
      the command line.
      
      All arch Makefiles that used the old variables has been updated.

      It is now possible to assign options to AS, CC and LD
      on the command line - which is only used when building modules.
      
      {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
      in the arch makefiles, thus users had no way to specify
      additional options to AS, CC, LD when building modules

      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-baseonly · d6f4ceb7
      Andi Kleen authored
      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.

      kbuild: Clean up and speed up the localversion logic · 09155120
      Michal Marek authored
      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 LOCALVERSION handling to match description · d5eda75f
      Andy Whitcroft authored
      In the commit below the version string handling was modified, adding
      a '+' where no other version information was supplied:
      
          commit 85a256d8
          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.

      Add a target to use the Coccinelle checker · 74425eee
      Nicolas Palix authored
      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.

      perf tools: Allow building perf source tarballs on non-configured tree · bafb6747
      Arnaldo Carvalho de Melo authored
      So that we don't require that the kernel be configured first, and as we
      don't use KERNELRELEASE at all in the -src-pkg targets, we need o add a
      new wildcard for targets ending in src-pkg:
      
      On a make mrproper'ed kernel we get this without this patch:

      From the last comment, arch makefile will override vmlinux. It seems
      vmlinux will not be checked by `make'. But from my test, although
      `all:' will be re-defined in arch Makefile (ARM arch), vmlinux will
      still be checked and the commands associated will be executed. Should
      we use another word instead of "overridden"?
