From bf4bc9021eadfd17047aed7d9a2ae73828f06728 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 6 Feb 2013 19:19:16 +1100 Subject: [PATCH] kvm tools: powerpc: Only emit TB freq if it's non-zero The kernel can handle a missing timebase-frequency property much better than one that claims zero.
