kernel.h: move READ/WRITE definitions to <linux/types.h>
Patch series "kernel.h: Move out a couple of macros and constants".
kernel.h hosts a couple of macros and constants that may be better placed.
Do that. Also add missing documentation. No functional changes
intended.
This patch (of 2):
Headers shouldn't be forced to include <linux/kernel.h> just to
gain these simple constants.
