That was fixed in the other patch you already ack'd  :)

http://git.kernel.org/cgit/linux/kernel/git/paulg/init.git/tree/x86-don-t-add-new-__cpuinit-users-to-Merrifield-plat.patch

I made the tangier fix a separate patch since it had a separate
introductory commit, and also actually had the section mismatch.

Paul.
