[PATCH 0/3] RFC: ARM section mapping debug prints

[Linus Walleij]

I just toss this out there to see if there is any general
interest. What the patches do is provide a printout of all
the very early section mappings right before the kernel
switches to execute from virtual memory.

I did this as part of troubleshooting KASan to see if the
problem was related to early boot and early section
mapping. It wasn't.

However if people find this useful I can polish it up with
your review comments and submit it to Russells patch tracker.
