From b3d7336db553d318e7ec042eb50a70d307013339 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 21 Jan 2011 15:29:44 -0800 Subject: x86: Move llc_shared_map out of cpu_info cpu_info is already with per_cpu, We can take llc_shared_map out of cpu_info, and declare it as per_cpu variable directly. So later referencing could be simple and directly instead of diving to find cpu_info at first. Also could make smp_store_cpu_info() much simple to avoid to do save and restore trick.
