KVM: PPC: Book3S HV: Increase timeout for grabbing secondary threads
Occasional failures have been seen with split-core mode and migration where the message "KVM: couldn't grab cpu" appears. This increases the length of time that we wait from 1ms to 10ms, which seems to work around the issue. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
