Subject: Re: [PATCH] powerpc/mm: Move page table dump into powerpc subdirectory

It's not powerpc specific. x86, arm, arm64 and s390 all have it.

But, I notice we somehow got the name wrong :}

All the other arches call it "kernel_page_tables".

So we probably should rename it to match the other arches. I would take
a patch for that.
