[PATCH] mm: pagealloc: fix continued prints in show_free_areas

[PATCH] mm: pagealloc: fix continued prints in show_free_areas

[Mark Rutland]

Recently, printk was reworked in commit:

  4bcc595ccd80decb ("printk: reinstate KERN_CONT for printing continuation
  lines")

As of this commit, printk calls missing KERN_CONT will have a linebreak
inserted implicitly.

In show_free_areas, we miss KERN_CONT in a few cases, and as a result
prints are unexpectedly split over a number of lines, making them
difficult to read (in v4.9-rc1).

This patch uses pr_cont (with uits implicit KERN_CONT) to mark all
continued prints that occur withing a show_free_areas() call. Note that
show_migration_types() is only called by show_free_areas().
Depending on CONFIG_NUMA a printk after show_node() may or may not be a
continuation, but follows an explicit newline if not (and thus marking
it as a continuation should not be harmful).

I think this was already fixed:
