Subject: weird DirectMap2M accounting.
Date: Wed, 6 Jan 2016 18:55:27 -0500	[thread overview]
Message-ID: <20160106235527.GA14135@codemonkey.org.uk> (raw)

I just spotted this in /proc/meminfo on an old Core2 machine with 4G.

DirectMap2M:    18446744073709543424 kB

Looks like we subtracted 8192 from 0 somewhere.

Should split_page_count() be checking that direct_pages_count > 0 ?

	Dave
