module_param()?? We can't compile kernel/workqueue.c as a module and
hence i went with #define + a variable with functions to set/reset it...

I am not looking to update all existing workqueues to use it but workqueues
which are affecting power for us... And if there are some very very
performance critical ones, then we must better use queue_work_on() for
them to make it more clear.
