Hi

> It is useful to verify a hugepage-aware application is using the expected
> pagesizes for its memory regions. This patch creates an entry called
> KernelPageSize in /proc/pid/smaps that is the size of page used by the
> kernel to back a VMA. The entry is not called PageSize as it is possible
> the MMU uses a different size. This extension should not break any sensible
> parser that skips lines containing unrecognised information.
