[PATCH] i386/x86-64 Correct for broken MCFG tables on K8 systems
They report all busses as MMCONFIG capable, but it never works for the internal devices in the CPU's builtin northbridge. It just probes all func 0 devices on bus 0 (the internal northbridge is currently always on bus 0) and if they are not accessible using MCFG they are put into a special fallback bitmap. On systems where it isn't we assume the BIOS vendor supplied correct MCFG. Requires the earlier patch for mmconfig type1 fallback Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
