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.
