[Xen-devel] [PATCH] asm,x86: Set max CPUs to 512 instead of 256.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Contemporary servers sport now 480 CPUs or such. We should crank
up the default amount of CPUs to a higher level to take advantage
of this without having the distro to use 'max_phys_cpus' override.
