	Our guest systems need to know by how much the timebase increases every second, so there usually is a "timebase-frequency" property in the cpu leaf of the device tree. This property is missing in OpenBIOS. With qemu, Linux's fallback timebase speed and qemu's internal timebase speed match up. With KVM, that is no longer true. The guest is running at the same timebase speed as the host. This leads to massive timing problems. On my test machine, a "sleep 2" takes about 14 seconds with KVM enabled. This patch exports the timebase frequency to OpenBIOS, so it can then put them into the device tree. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2008-12-16	target-ppc: Enable KVM for ppcemb.	aurel32
	Implement hooks called by generic KVM code. Also add code that will copy the host's CPU and timebase frequencies to the guest, which is necessary on KVM because the guest can directly access the timebase.
