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.
