Does not appear with an allmodconfig.
Care to send me your .config then I may take a look.

The warnings are the kernel being much more anal with respect to use
of __init sections and friends and you can for normal use ignore them.
They usually find bugs in errorhandling which seldom trigger and
the bugs has been there for ages in most cases - but it is onyl now
we detect them.
