From 67ff575ee8d20508f5e2ea82ac97442130693e54 Mon Sep 17 00:00:00 2001 From: Marvin Liu Date: Tue, 11 Aug 2015 14:49:23 +0800 Subject: [PATCH] examples/vm_power: fix physical core mask Host cpu mapping structure can only support 64 cpus. When run vm_power sample on platform with more than 64 cpus, will generate improper physical core mask. After limited supported host cpus to 64 will fix this issue.
