Hi, FYI I have merged patches 1, 6 and 7 of this patchset. They look fine and are worthwhile fixes on their own.

Hi Thomas, The Intel(x86) CPUs have a separate address space for "IO", but the ARM architecture only has "memory", so all IO devices are accessed as if they were memory. Which means ARM does not support isolated IO. Here is a related discussion on ARM's forum. https://community.arm.com/support-forums/f/architectures-and-processors-forum/52046/how-to-read-write-an-i-o-port-in-aarch64 Thus, we adapt MMIO only after this patch.

It's just open coded and matches. Note that Thomas said that his version apparently failed for some reason, but hey maybe we should try again.
