Please provide more justification for NR_SECONDARY_PAGETABLE in the changelog. Specially, answer the questions that were asked in the previous version: 1. Why not piggyback NR_PAGETABLE? 2. Why a "generic" NR_SECONDARY_PAGETABLE instead of NR_VIRT_PAGETABLE? It doesn't have to be super long, but provide enough info so that reviewers and future readers don't need to go spelunking to understand the motivation for the new counter type. And it's probably worth an explicit Link to Marc's question that prompted the long discussion in the previous version, that way if someone does want the gory details they have a link readily available.
