Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-fixes
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-fixes: kbuild: create the source symlink earlier in the objdir scripts: add x86 64 bit support to the markup_oops.pl script scripts: add x86 register parser to markup_oops.pl kbuild: add sys_* entries for syscalls in tags kbuild: fix tags generation of config symbols bootgraph: fix for use with dot symbols kbuild: add vmlinux to kernel rpm kbuild,setlocalversion: shorten the make time when using svn
