From f34e3b61f2be9628bd41244f3ecc42009c5eced5 Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Thu, 19 Jul 2007 01:48:13 -0700 Subject: use the new percpu interface for shared data Currently most of the per cpu data, which is accessed by different cpus, has a ____cacheline_aligned_in_smp attribute. Move all this data to the new per cpu shared data section: .data.percpu.shared_aligned. This will seperate the percpu data which is referenced frequently by other cpus from the local only percpu data.
