Changeset 1.403.15.8 2002/6/05 davej@suse.de [PATCH] large x86 setup cleanup.
Patrick Mochel did a great job here at splitting up some of the larger messy parts of arch/i386/kernel/setup.c, and introduced a nice abstraction which gives us a much nicer way to ensure we can add workarounds for vendor specific bugs / features without polluting other vendor code paths.
Mark Haverkamp also brought this up to date for merging in my tree circa 2.5.14, and asides from 1-2 now fixed small thinkos, there haven't been any problems.
This also features a workaround for an errata item on stepping C0 of the Intel Pentium 4 Xeon, which isn't in your tree yet, where we must disable the hardware prefetcher to ensure sane operation.
arch/i386/kernel/setup.c 1.41.1.16 2002/06/03 10:10:19 davej@suse.de large x86 setup cleanup.
