[PATCH] x86: Compress stack unwinder output
The unwinder has some extra newlines, which eat up loads of screen
space when it spews. (See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=137900
for a nasty example).
warning_symbol-> and warning-> already printk a newline, so don't add one
in the strings passed to them.
[AK: redone for new code]
