It looks good to me. Acked-by: Suresh Siddha <suresh.b.sid...@intel.com> Sasha, can you please give this a try? > but it does *not* fix the fact > that the MTRR start/end model is broken.

I guess we should be checking for those limits in pat.c, especially bits above 52 are ignored by the HW and they can easily cause conflicting aliases with other valid regions. I will get back with a different patch to fix this. thanks, suresh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
