From af1bff4f1d117f99ad8a88e6532baff475fb44a5 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 10 Dec 2007 07:40:54 -0800 Subject: [PATCH] Revert "PCI: fix IDE legacy mode resources" This reverts commit fd6e732186ab522c812ab19c2c5e5befb8ec8115, which helped up things on MIPS, but was wrong for everything else. As Ralf Baechle puts it: "It seems the whole MIPS resource managment is complicated enough (out of necessity) that only a few people actually grok it. Ioports being actually memory mapped on MIPS only makes the confusion worse, sigh."
