Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6: initramfs: Fix build break on symbol-prefixed archs initramfs: fix initramfs size calculation initramfs: generalize initramfs_data.xxx.S variants scripts/kallsyms: Enable error messages while hush up unnecessary warnings scripts/setlocalversion: update comment kbuild: Use a single clean rule for kernel and external modules kbuild: Do not run make clean in $(srctree) scripts/mod/modpost.c: fix commentary accordingly to last changes kbuild: Really don't clean bounds.h and asm-offsets.h
