[Qemu-devel] [PATCH] vl: remove (max_cpus > 255) check from smp_parse

[Alexey Kardashevskiy]

Since modern POWER7/POWER8 chips can have more that 256 CPU threads
(>2000 actually), remove this check from smp_parse.

The CPUs number is still checked against machine->max_cpus and this check
should be enough not to break other archs.
