Subject[PATCH] printk(*KERN_INFO* "Freeing unused kernel/initrd mem")
Date
This patch changes loglevel of "Freeing unused kernel/initrd mem" printks
to KERN_INFO in several archs.

Primary purpose of this patch is to make KERN_WARNING and
KERN_INFO log levels closer to their original meaning.
Today they are quite far from what was intended.
Just look what kernel writes at the WARNING level
each time you boot your box!

Since wholesale patch wasn't accepted, I'll send most obvious
parts split in small pieces now.

If something wrong with the patch or with the way I'm trying to
push it into mainstream kernel, let me know.
