[PATCH] mm: be more informative in OOM task list

From: Rodrigo Freire
Date: Sun Jul 01 2018 - 12:10:00 EST

The default page memory unit of OOM task dump events might not be
intuitive for the non-initiated when debugging OOM events. Add
a small printk prior to the task dump informing that the memory
units are actually memory _pages_.
