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: modpost: remove all traces of cpuinit/cpuexit sections init.h: remove __cpuinit sections from the kernel
