From 4f07118f656c179740cad35b827032e2e29b1210 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 29 Aug 2005 12:46:22 -0700 Subject: [SPARC64]: More fully work around Spitfire Errata 51. It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata. So move them out-of-line, and explicitly put them into a "branch always, predict taken" delay slot which should fully kill this problem. Signed-off-by: David S.
