[PATCH] x86: use KERN_CONT in dump_pagetable()

From: Jan Beulich
Date: Thu Aug 24 2017 - 05:34:11 EST


The lack of newlines in preceding format strings is a clear indication
that these were meant to be continuations of one another, and indeed
output ends up quite a bit more compact (and readable) that way.
