Merge branch 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull misc kbuild changes from Michal Marek: "The non-critical part of kbuild for 3.5 includes - two new coccinelle checks - fix for make deb-pkg to include generated headers in arch/*/include I have more make-deb-pkg fixes in the backlog, but these will likely have to wait for 3.6." * 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: builddeb: include autogenerated header files scripts/coccinelle: sizeof of pointer scripts/coccinelle: address test is always true
