Merge branch 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull misc kbuild updates from Michal Marek:
- deb-pkg:
+ module signing fix
+ dtb files are added to the package
+ do not require `hostname -f` to work during build
+ make deb-pkg generates a source package, bindeb-pkg has been
added to only generate the binary package
- rpm-pkg packages /lib/modules as well
- new coccinelle patch and updates to existing ones
- new stackusage & stackdelta script to collect and compare stack usage
info (using gcc's -fstack-usage)
- make tags understands trace_*_rcuidle() macros
- .gitignore updates, misc cleanups
* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: (27 commits)
deb-pkg: add source package
package/Makefile: move source tar creation to a function
scripts: add stackdelta script
kbuild: remove *.su files generated by -fstack-usage
.gitignore: add *.su pattern
scripts: add stackusage script
kbuild: avoid listing /lib/modules in kernel spec file
fallback to hostname in scripts/package/builddeb
coccinelle: api: extend spatch for dropping unnecessary owner
deb-pkg: simplify directory creation
scripts/tags.sh: Include trace_*_rcuidle() in tags
scripts/package/Makefile: rpmbuild is needed for rpm targets
Kbuild: Add ID files to .gitignore
gitignore: Add MIPS vmlinux.32 to the list
coccinelle: simple_return: Add a blank line
coccinelle: irqf_oneshot.cocci: Improve the generated commit log
coccinelle: api: add vma_pages.cocci
