Subject: [PATCH 6/6] kvm tools: powerpc: Only emit TB freq if it's non-zero
Date: Wed, 6 Feb 2013 19:19:16 +1100 [thread overview]
Message-ID: <1360138756-1991-6-git-send-email-michael@ellerman.id.au> (raw)
In-Reply-To: <1360138756-1991-1-git-send-email-michael@ellerman.id.au>
The kernel can handle a missing timebase-frequency property much better
than one that claims zero.
