Subject: kernel.h: drop unneeded <linux/kernel.h> inclusion from other headers

Patch series "kernel.h further split", v5.

kernel.h is a set of something which is not related to each other and
often used in non-crossed compilation units, especially when drivers need
only one or two macro definitions from it.


This patch (of 7):

There is no evidence we need kernel.h inclusion in certain headers.  Drop
unneeded <linux/kernel.h> inclusion from other headers.
