    I know you are looking to have support for PowerPC.

    Isn't this a PowerPC problem? Why penalize other architectures?

    Do you see anything wrong with the code itself?

    I started this thread with the PowerPC develoeprs on your request.
    "RFC on writel and writel_relaxed"

    They are looking into adding the relaxed API support. Support can come
    in later. Why block this change now?

    benh@kernel.crashing.org:
    "I've been wanting to implement the relaxed accessors for a while but
    was battling with this to try to also better support WC, and due to
    other commitments, this somewhat fell down the cracks."

    I have seen four different responses on this thread. Since this is an
    architecture change it will take a while to get the semantics right.
    It won't happen in the new few days.
