Hi,

> It seems that Xen for ARM is not support SMP boot by default since "max_phys_cpus" is not set?

max_phys_cpus allows use to restrict the number of cpus handled by Xen.
It's only used to set NR_CPUS. If the former is not set, Xen will use
128 as default value (see include/asm-arm/config.h).

Cheers,
