Subject: x86/mm: Use pr_cont() in dump_pagetable()
X-Git-Tag: v4.14-rc1~161^2~1
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=39e48d9b128abbd2ea9b8403bb1e2693323db2f4;p=linux-block.git

x86/mm: Use pr_cont() in dump_pagetable()

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.

Switch other plain printk()-s in the function instances to pr_info(),
as requested.
