Subject[git patches] kbuild fixes for -rc
Hi Linus.
Please pull following fixes from the kbuild tree.

git pull git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git

The modpost change repairing mips is the biggest change
but boils down to a fix for a binutils issue.
Other fixes are more cornercases.
Also the fix from Randy brings down the number of false
positives section mismatch warnings with allmodconfig.

diffstat + full log + full diff added below.

kbuild: Do not overwrite makefile as anohter user

Change the conditional of the outputmakefile rule to be evaluated entirely
in make, and add a conditional to not touch the generated makefile when e.g.
running 'make install' as root while the build was done as non-root. Also
adjust the comment describing this, and move the message printing and
redirection to mkmakefile.

kbuild: removing .tmp_versions considered harmful

Remove *.mod files but not .tmp_versions for external builds

When "make install" is run as root, .tmp_versions is re-created and
becomes owned by root. Subsequent "make" run by user fails because
.tmp_versions cannot be removed.

kbuild: fix modpost segfault for 64bit mipsel kernel

64bit mips has different r_info layout. This patch fixes modpost
segfault for 64bit little endian mips kernel.
