* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6: mkuboot.sh: Fail if mkimage is missing gen_init_cpio: checkpatch fixes gen_init_cpio: Avoid race between call to stat() and call to open() modpost: Fix address calculation in reloc_location() Make fixdep error handling more explicit checksyscalls: Fix stand-alone usage modpost: Put .zdebug* section on white list kbuild: fix interaction of CONFIG_IKCONFIG and KCONFIG_CONFIG kbuild: export linux/{a.out,kvm,kvm_para}.h on headers_install_all kbuild: introduce HDR_ARCH_LIST for headers_install_all headers_install: check exit status of unifdef gen_init_cpio: remove leading `/' from file names scripts/genksyms: fix header usage fixdep: use hash table instead of a single array
