From: Oleksandr Tyshchenko <oleksandr_tyshche...@epam.com>
The number of vCPUs used for the IOREQ configuration (machine->smp.cpus)
should really match the system value as for each vCPU we setup a dedicated
evtchn for the communication with Xen at the runtime. This is needed
for the IOREQ to be properly configured and work if the involved domain
has more than one vCPU assigned.
Set the number of current supported guest vCPUs here (128) which is
defined in public header arch-arm.h. And the toolstack should then
pass max_vcpus using "-smp" arg.
