Subject: [PATCH] numa_emulation: fix cpumask_of_node()
Date: Fri, 16 Mar 2012 20:28:11 +0100	[thread overview]
Message-ID: <1331926091-22548-2-git-send-email-aarcange@redhat.com> (raw)
In-Reply-To: <1331926091-22548-1-git-send-email-aarcange@redhat.com>

Without this fix the cpumask_of_node() for a fake=numa=2 is:

cpumask 0 ff
cpumask 1 ff

with the fix it's correct and it's set to:

cpumask 0 55
cpumask 1 aa
