A commit references this bug: Author: kib Date: Tue Nov 28 09:34:43 UTC 2017 New revision: 326311 URL: https://svnweb.freebsd.org/changeset/base/326311 Log: Fix index calculation for the page table pages for efirt 1:1 map. Stop issuing pre-assigned number to enumerate all page table pages, the assignment is incorrect. Instead automatically calculate the next unused index. This index in fact does not serve any purpose except to be unique to satisfy vm_page_grab() interface, we do not look up the page by the index later.

batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
Fixed years ago, no need for MFC any longer
