Some recent arm64 cores have a facility that allows the page
table walker to track the dirty state of a page. This makes it
really efficient to perform CMOs by VA as we only need to look
at dirty pages.

I think this may have caused a regression for the Marvell AC5X
board(s). I found that v2023.07 locked up at boot but v2023.01 was
fine. The lockup seemed to be in the 'Net:' init probably just as the
mvneta driver was being initialised.
A git bisect led me to this change although for this specific change
instead of the lockup I get a crash so maybe I'm actually hitting a
different issue.
Any thoughts as to why this may have caused problems?
Not really. What CPUs does this platform have? What is the offending
driver doing to trigger the issue? Can you provide some level of
tracing?
