Subject: [patch 3/8 v5] x86, UV: allow for non-consecutive sockets
Date: Tue, 21 Jun 2011 07:21:28 -0500	[thread overview]
Message-ID: <20110621122242.363757364@sgi.com> (raw)
In-Reply-To: 20110621122125.688884227@sgi.com

[-- Attachment #1: tlb_uv_nonconsecsockets --]
[-- Type: text/plain, Size: 828 bytes --]

Fix for the topology in which there is a socket 1 on a blade with no socket 0.

Signed-off-by: Cliff Wickman <cpw@sgi.com>
---

Only call make_per_cpu_thp() for present sockets.
We have only seen this fail for internal configurations.
