    Subjectpatch disabling use of PSE on Atom CPUs with a certain erratum
    In commit 7a0fc404ae663776e96db43879a0fa24fec1fa3a you
    disable use of PSE, but I wonder how this can take any effect on
    64-bit CPUs, as they use large pages during early boot already.
    Those pages, when use of PSE gets disabled, will get broken up
    into 4k pages in phys_pmd_init(), thus actually increasing the
    chances that you hit the erratum.

    What am I missing?
