[PATCH] Finally eradicate CONFIG_HOTPLUG
Stephen Rothwell
sfr at canb.auug.org.au
Mon May 20 23:49:35 EDT 2013
Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off. Remove all the remaining references to it.
