Since printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited.

Is this new include really needed? The printk_ratelimited() definition
is in printk.h...
Thanks,
Rusty.

Yes.
printk_ratelimited() needs DEFINE_RATELIMIT_STATE() which is defined
in ratelimit.h.

Yech. I'm assuming that making printk.h include ratelimit.h makes a
nasty mess?
Thanks,
Rusty.

Yup.
I proposed moving the <foo>_ratelimited dclarations to
ratelimited.h without any comment.
