Subject: [PATCH 0/2] fdt: A couple of no-map fixes
Date: Fri, 15 Jan 2021 11:45:42 +0000	[thread overview]
Message-ID: <20210115114544.1830068-1-qperret@google.com> (raw)

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
