Subject: [PATCH v1 4/4] examples/power: increase MAX_CPUS to 256
Date: Thu, 22 Nov 2018 17:02:20 +0000	[thread overview]
Message-ID: <20181122170220.55482-5-david.hunt@intel.com> (raw)
In-Reply-To: <20181122170220.55482-1-david.hunt@intel.com>

Increase the number of addressable cores from 64 to 256. Also remove the
warning that incresing this number beyond 64 will cause problems (because
of the previous use of uint64_t masks). Now this number can be increased
significantly without causing problems.
