Subject: [PATCH 4.14 005/137] x86/numa_emulation: Fix emulated-to-physical node mapping
Date: Tue, 2 Oct 2018 06:23:26 -0700 [thread overview]
Message-ID: <20181002132458.779929451@linuxfoundation.org> (raw)
In-Reply-To: <20181002132458.446916963@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
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.
