[PATCH 1/6] mm/page_alloc: use appropriate printk priority level

From: Mandeep Singh Baines
Date: Wed Jan 26 2011 - 18:31:41 EST


printk()s without a priority level default to KERN_WARNING. To reduce
noise at KERN_WARNING, this patch set the priority level appriopriately
for unleveled printks()s. This should be useful to folks that look at
dmesg warnings closely.
