Here are a couple of patches for the arm64 pagetable dump code.
The first patch is the final reusable ptdump patch, rebased to v4.7-rc1, as per
your request . Other than the rebase, I have made no changes.
The second patch addresses an ambiguity in the dump output, in that we cannot
determine whether a span of block entries exists at the PGD, PUD, or PMD level.
It's logically unrelated to patch 1, and the two should apply independently,
but I've put them in a series so that I can call that out, and to avoid the
inevitable confusion with patches that appear to intersect.
I've given them both a spin on Juno R1 with v4.7-rc1 defconfig, fiddling with
the page size and number of levels. So far everything seems to work as
