Differences in logging.h to original kernel.h
were done for cleanliness and checkpatch.

o comment added for purpose of struct va_format
o function no_print() broken into multiple lines
o #ifdef CONFIG_PRINTK vprintk/printk block
  and #else block moved together
o printk_ratelimit and related now have another
  CONFIG_PRINTK and #else block
o pr_debug and pr_debug_ratelimit statement
  expressions are broken into multiple lines

If you want a nearly identical line count
for logging.h, followed by a cleanup only pass
of logging.h, I'll do that.

Is that what you want?

I didn't recompile and verify this second patch
as all I did was remove the unused for now
pr_<level>_once macros I added.

It takes my slowish setup quite a while to do
full compiles for allyesconfig/allmodconfig/
allnoconfig/defconfig/CONFIG_EMBEDDED/CONFIG_PRINTK=n
variants though so it'd be another day or so before
it'd be verified.
