Subject: Re: [PATCH 4/5] x86, mm: Add set_memory_wt() for WT
Date: Sun, 07 Sep 2014 11:49:05 +0300 [thread overview]
Message-ID: <540C1C01.1000308@plexistor.com> (raw)
In-Reply-To: <1409857025.28990.125.camel@misato.fc.hp.com>
I think that what confused Andy (or at least me) is the documentation in Documentation/x86/pat.txt
If it's possible, can you please update pat.txt as part of the patch?
Thank you,
Yigal
