CVS commit: src/sys/arch/amd64/stand/prekern

Module Name:    src
Committed By:   maxv
Date:           Sun Nov 26 14:29:48 UTC 2017

Modified Files:
        src/sys/arch/amd64/stand/prekern: mm.c

Log Message:
Oh, damn. Obviously I forgot one case here: an already-mapped region could
be contained entirely in the region we're trying to create. So go through
another round. While here add mm_reenter_pa, and make sure the va given to
mm_enter_pa does not already point to something.
