In the context of a KVM/arm64 thread [1], it became apparent that the difference in behaviour of EFI and DT with respect to no-map regions was something worth fixing.
Rob pointed out in that thread that a couple of patches in this area had been sent but still needed to be integrated together, which is basically what this series attempts to do. - Patch 01 is a generic fix that should make sense on its own; - Patch 02 allows the kernel to have a saner behaviour with a broken DT. This one had a small rebase conflict (caused by patch 01). I tested it in qemu and everything is looking good, the error message shows up in dmesg when it should.
