    It should be noted what broke was the non-portable constructs in the generic
    suspend code.

    In particular using __pa() outside of architecture code is not allowed.
    Using virt_to_phys() on addresses not part of the kernel's linear mapping is
    not generically supported.

    text/data are not required to be part of the kernel's linear mapping.

    This patchset now causes all code using these non-portable constructs to
    fail on x86_64. Which I think is a good thing so we can more easily
    spot these kinds of problems.

    Patches 15 and 16 appear to make the swpsuspend code rely on portable
    constructs. I will let Vivek reply to the amount of testing he has
    done in this area.
