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
