Looks like Palmer's already reviewed it.  One additional request: could
you update the VM layout debugging messages in arch/riscv/mm/init.c to
include this new area?

Sure, I'll send that as a follow-up!

Thanks.

Related; Other archs, e.g. arm64, has moved away from dumping the VM 
layout (commit 071929dbdd86 ("arm64: Stop printing the virtual memory 
layout")), and instead rely on _PTDUMP. Going forward that probably 
applies to riscv as well!

For the specific case of the page table dumper: we're waiting for the 
generic ptdump patchset to be merged first - hopefully for v5.6.  The 
RISC-V integration patches against it were posted to the lists back in 
October.  But, to me, that targets a different use-case than the VM layout 
debug print code.
