I have now tested this against xen-testing 9735. Without the patch,

with a domU kernel configured with CONFIG_DEBUG_SOFTLOCKUP disabled

script which does lots of cpu hotplug/removal will hang (cpu
hotplug/removal stresses the RCU synchronize_sched function). With the
patch, the script doing cpu hotplug/removal runs for as long as I have
let it so far (thousands of hotplugs).
Okay, the patch looks good to me. I'll apply to our trees. Thanks.
