* [REVIEW for merge] kbuild updates including silence of section mismatch check

From: Sam Ravnborg @ 2008-02-02 20:35 UTC (permalink / raw)
  To: linux-kbuild, LKML; +Cc: Andrew Morton

I have queued up 10 patched for kbuild.git.
As a few are new I post them for review here
before pushing to Linus.

The patchset from Mathieu causes the hing number of
lines changed - the rest is smaller stuff.

The most visible change is that I have made all the section mismatch
go away and in the end of the build modpost report the number
of section mismatch warnings and how to see detail.

The typical output is now:

modpost: Found 35 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'

And CONFIG_DEBUG_SECTION_MISMATCH cannot be set
from the config anymore so we are not noisy in typical
allyesconfig builds.

When we are down to an acceptable number of warnings modpost
will start to be vocal again. The acceptable number is somewhere
below 20 for an allyseconfig/allmodconfig build.

All patches are pushed out to kbuild.git.

See below for more details and a combined patch.
Individual patches will be sent to kbuild only (and no cc:)

	Sam

Bryan Wu (1):
      kbuild: add svn revision information to setlocalversion

Geert Uytterhoeven (1):
