    Quoting that text: "In order to be able to suppress the use of SRAT
    tables that 32-bit Linux can't deal with (possibly leading to a non-
    bootable system, without disabling ACPI altogether), move the
    "numa=" option handling to common code."

    To me it says just that. And of course, not every system with a
    not understood SRAT would be yielded non-bootable, hence the
    wording "possibly leading to ...".
