Subject: Section mismatch: kernel/workqueue.c

During compilation of the linus tree the following warnings are encountered:

WARNING: kernel/built-in.o(.data+0x2480): Section mismatch in
reference from the variable workqueue_cpu_callback_nb.14223 to the
function .devinit.text:workqueue_cpu_callback()
The variable workqueue_cpu_callback_nb.14223 references
the function __devinit workqueue_cpu_callback()
If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

This fix is to correct the following warning during compilation.
Based on my "elementary" analysis, as it is called from other
non-__init functions, this function cannot be declared as __devinit(),
correct?   Please comment.   Thanks :-).
