From: Brice Goglin Date: Mon, 21 Jul 2008 08:26:25 +0000 (+0200) Subject: myri10ge: use ioremap_wc X-Git-Tag: v2.6.27-rc1~860^2~3^2~52 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7f80993a38f0354a8ad821bcd9335b47a464357;p=linux-2.6 myri10ge: use ioremap_wc Switch to ioremap_wc(). We keep the MTRR code since ioremap_wc() will use UC_MINUS when falling back to uncachable, and thus let the MTRR WC take precedence. Also rename the error path better.
