From 663f2f51b10e55a9093a0bc458dadfbaf1705c31 Mon Sep 17 00:00:00 2001 From: Chao Peng Date: Thu, 26 May 2016 10:03:13 +0800 Subject: [PATCH] x86/psr: make opt_psr persistent opt_psr is now not only used at booting time but also at runtime. More specifically, it is used to check CDP switch in psr_cpu_init() which can potentially be called in CPU hotplug case.
