From 981752df71cfdab8096cb44a76a9b597cdde8796 Mon Sep 17 00:00:00 2001 From: Felipe Franciosi Date: Thu, 13 Mar 2014 14:34:20 +0000 Subject: [PATCH] mtip32xx: Set queue bounce limit commit 1044b1bb9278f2e656a1a7b63dc24a59506540aa upstream. We need to set the queue bounce limit during the device initialization to prevent excessive bouncing on 32 bit architectures.
