    Subject[PATCH 0/2] faking and fixing the NUMA SLIT
    Date
    The problem with NUMA distances in the SLIT is that they are often wrong, oh 
    wait they aren't there at all because the BIOS didn't create a SLIT since
    Windows does not use it.  If Linux does not find a slit it just says the
    distance to local=10 and remote=20 according to ACPI spec.  The problem is
    when we have a 4P system (or larger), there is generally one node where we
    have two hops and its distance should be >20.

    Following are patches to first fake the SLIT in the ACPI code and then add
    ability to write the distances from sysfs.
