[PATCH] i386: Fix Cyrix MediaGX detection
The old Cyrix 5520 CPU detection code relied upon the PCI layer setup being done earlier than the CPU setup, which is no longer true. Fortunately we know that if the processor is a MediaGX we can do type 1 pci config accesses to check the companion chip. We thus do those directly and from this find the 5520 and implement the workarounds for the timer problem Original report from takada@mbf.nifty.com, I sent a proposed patch which Takara then corrected, tested and sent back to the list on 10th January. Submitting for merging as it seems to have been missed AK: Changed to use pci-direct.h and fix warning for !CONFIG_PCI (later AK: originally from akpm) Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de> Cc: Andi Kleen <ak@suse.de> Cc: <takada@mbf.nifty.com> Cc: Jordan Crouse <jordan.crouse@amd.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
