Subject: [PULL] kbuild fixes
Hi Linus.
A greater batch of kbuild fixes than usual due to my absense for
a few months.
I included the change to include/init.h as it allows
people to start suing these without getting into
merge order troubles and they are simple additions.
The rest is trivial fixes and incompatibility with
older perl version. The full diff does not look scary.
I expect at least one more pull as I have not been through
all patches yet - and need to visit bugzilla too.
Details follows.
Please pull - thanks!
Sam
