Subject: [Qemu-devel] [PATCH] vl: remove (max_cpus > 255) check from smp_parse
Date: Mon, 25 Nov 2013 14:39:10 +1100	[thread overview]
Message-ID: <1385350750-21468-1-git-send-email-aik@ozlabs.ru> (raw)

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.
