Subject: [PATCH AUTOSEL 3.18 03/29] x86/numa_emulation: Fix emulated-to-physical node mapping
Date: Mon, 17 Sep 2018 03:05:38 +0000 [thread overview]
Message-ID: <20180917030533.592-3-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180917030533.592-1-alexander.levin@microsoft.com>
From: Dan Williams <dan.j.williams@intel.com>
[ Upstream commit 3b6c62f363a19ce82bf378187ab97c9dc01e3927 ]
Without this change the distance table calculation for emulated nodes
may use the wrong numa node and report an incorrect distance.
