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.

Thanks,
Quentin
