initconst adjustments
- add .init.rodata to INIT_DATA, and group all initconst flavors together - move strings generated from __setup_param() into .init.rodata - add .*init.rodata to modpost's sets of init sections - make modpost warn about references between meminit and cpuinit as well as memexit and cpuexit sections (as CPU and memory hotplug are independently selectable features) Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
