From 8cd1943bf0e87f467a1b498c63483f70b18b43d7 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 21 Apr 2015 13:46:06 -0700 Subject: [PATCH] fusion: remove dead MTRR code If and when this gets enabled the driver could should split up IO memory space properly and that is quite a bit of work. Just remove the uncommented dead MTRR code then. There are a few motivations for this: a) Take advantage of PAT when available b) Help bury MTRR code away, MTRR is architecture specific and on x86 its replaced by PAT c) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442e titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()") Signed-off-by: Luis R.
