include/linux/kernel.h: Move logging bits to include/linux/printk.h
Move the logging bits from kernel.h into printk.h so that there is a bit more logical separation of the generic from the printk logging specific parts. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
