Pull misc kbuild updates from Michal Marek:
"In the kbuild misc branch, I have:

/sbin/installkernel
- make deb-pkg: debuginfo split, correct kernel image path for
parisc, mips and powerpc and a couple more minor fixes
- New coccinelle check"

scripts/checkkconfigsymbols.sh: replace echo -e with printf
Provide version number for Debian firmware package
coccinelle: replace 0/1 with false/true in functions returning bool
deb-pkg: add a hook argument to match debian hooks parameters
deb-pkg: fix installed image path on parisc, mips and powerpc
deb-pkg: split debug symbols in their own package
deb-pkg: use KCONFIG_CONFIG instead of .config file directly
rpm-pkg: add generation of kernel-devel
