    Looking back at the mail tread, I'd say there are people who have legitimate
    usecases. However, this may not be the most important question. At the moment,
    the /dev/mem interface is broken (it doesn't implement the specification
    correctly), and my patchset fixes it.

    If there are no technical objections, I'd like to ask for an Acked-by from all
    involved people.

    @Ingo: you can also send a patchset that rips off the /dev/mem driver
    completely if you believe that would get through. I'm completely fine with
    that, because then the /dev/crash driver will no longer be a semi-broken re-
    implementation of an existing in-kernel driver, so I'll be able to post it as
    a new driver.

    But please make a decision either way.
