From 79e453d49bd49ba1b576f89310cc565c9e4ca379 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 19 Sep 2006 08:15:22 -0700 Subject: Revert mmiocfg heuristics and blacklist changes This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and 40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.
