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
