From 088ba34c92055547ef4cc862a863334c01d9a304 Mon Sep 17 00:00:00 2001 From: "Stephen M. Cameron" Date: Thu, 26 Jul 2012 11:34:23 -0500 Subject: [PATCH] [SCSI] hpsa: use ioremap_nocache instead of ioremap I think ioremap() ends up being equivalent to ioremap_nocache by default, but we should signal our intent that these mappings should be non-cacheable.
