Author: alc Date: Sat Sep 30 18:07:46 2017 New Revision: 324126 URL: https://svnweb.freebsd.org/changeset/base/324126 Log: MFC r323785 Sync with amd64/arm/arm64/i386/mips pmap change r288256: Exploit r288122 to address a cosmetic issue. Since PV chunk pages don't belong to a vm object, they can't be paged out. Since they can't be paged out, they are never enqueued in a paging queue. Nonetheless, passing PQ_INACTIVE to vm_page_unwire() creates the appearance that these pages are being enqueued in the inactive queue. As of r288122, we can avoid this false impression by passing PQ_NONE.
