When the initial domain starts, it prints (depending on the amount of CPUs) a slew of XENBUS: Unable to read cpu state XENBUS: Unable to read cpu state XENBUS: Unable to read cpu state XENBUS: Unable to read cpu state which provide no useful information - as the error is a valid issue - but not on the initial domain. The reason is that the XenStore is not accessible at that time (it is after all the first guest) so the CPU hotplug watch cannot parse "availability/cpu" attribute.

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
