From 478c6e529e7bd7c6ef8994c55bd252c287c35893 Mon Sep 17 00:00:00 2001 From: Cliff Wickman Date: Mon, 16 Jan 2012 15:20:50 -0600 Subject: [PATCH] x86/UV2: Remove stale no-resources test for UV2 BAU This patch removes an unnecessary test for a no-destination-resources-available condition that looks like a destination timeout in UV1, but is separately distinguishable in UV2.
