Okay, I finally got around looking at this a little longer and
came up with the port update below. Specifically, I tried to merge
the good parts of the old kqemu wrapper:
- device cloning support on 5.x (multiple vms can use kqemu, tested
and seems to work)
- 4.x support (untested, I'm not sure if vm_map_user_pageable can
be used as a 1-to-1 replacement for vm_map_{un,}wire on 4.x, can
anyone here definitely say?)
- max_locked_pages calculation
Also:
- moved debug messages under debug.kqemu_debug sysctl
(do `sysctl debug.kqemu_debug=1' to enable)
- fixed a small bug
- added the amd64 ata irq mapping fix
Also untested on amd64.
