Merge branch 'cpuinit-delete' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull first stage of __cpuinit removal from Paul Gortmaker:
 "The two commits here 1) dummy out all the __cpuinit macros so that we
  no longer generate such sections, and then 2) remove all the section
  processing that we used to do for those sections.

  This makes all the __cpuinit and friends no-ops, so that we can remove
  the use cases of it at our leisure.  Expect stage 2, which does the
  tree wide removal sweep at the end of the merge window."

* 'cpuinit-delete' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
