Why not just add a pagesize={4K,2M,1G,...} field for every output? 

I think it's a bit misleading.  With THP at least we have 2M pages in
the MMU, but we're reporting in 4k units.

I certainly considered doing just what you're suggesting, though.  It's
definitely not a bad idea.  Certainly much more clear.

Een though the code is in task_mmu.c, I think that /proc/pid/numa_maps 
should be more representative of the state of vmas where any 
pagesize={4K,2M,1G,...} would be true rather than whether or not the mmu 
sees tham as large or small pages.  I actually don't see much difference 
between anon=50 pagemult=512 and anon=50 pagesize=2M, but I'd definitely 
recommend printing the field for every vma.
