Subject: [PATCH 1/2] init.h: Remove __dev* sections from the kernel

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

With the recent work to remove CONFIG_HOTPLUG, we are starting to get a
bunch of __devinit section warnings, despite CONFIG_HOTPLUG always being
enabled.  So, stop marking the sections entirely, by defining them away
the section markings in init.h
