Merge branch 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull misc kbuild updates from Michal Marek: "Non-critical kbuild changes: - make coccicheck improvements, but no new semantic patches this time - make rpm improvements - make tar-pkg change to include the architecture in the filename. This is a deliberate incompatibility, but nobody has complained so far and it is useful if you build for different architectures. It also matches what the deb-pkg and rpm-pkg targets produce. - kbuild documentation fix" * 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: rpm-pkg: Remove pointless set -e statements rpm-pkg: Always regenerate the specfile rpm-pkg: Do not write to the parent directory rpm-pkg: Do not package the whole source directory buildtar: Add ARCH to the archive name Coccinelle: Fix patch output when coccicheck is used with M= and C= Coccinelle: Add support to the SPFLAGS variable Coccinelle: Cleanup the setting of the FLAGS and OPTIONS variables Coccinelle: Restore coccicheck verbosity in ONLINE mode (C=1 or C=2) scripts/package/Makefile: compare objtree with srctree instead of test KBUILD_OUTPUT doc: change example to existing Makefile fragment scripts/tags.sh: Add magic for OFFSET and DEFINE
