11b50ccc0e Prior to r254304, we only began scanning the active page queue when the
amount of free memory was close to the point at which we would begin
reclaiming pages.  Now, we continuously scan the active page queue,
regardless of the amount of free memory.  Consequently, we are continuously
calling pmap_ts_referenced() on active pages.

Prior to this change, pmap_ts_referenced() would always demote superpage
mappings in order to obtain finer-grained reference information.  This made
sense because we were coming under memory pressure and would soon have to
begin reclaiming pages.  Now, however, with continuous scanning of the
active page queue, these demotions are taking a toll on performance.  To
address this problem, I have replaced the demotion with a heuristic for
periodically clearing the reference flag on superpage mappings.

348fe8d4ce Fix a limitation in bhyve that would limit the number of virtual machines to
the maximum number of VT-d domains (256 on a Sandybridge). We now allocate a
VT-d domain for a guest only if the administrator has explicitly configured
one or more PCI passthru device(s).

If there are no PCI passthru devices configured (the common case) then the
number of virtual machines is no longer limited by the maximum number of
VT-d domains.

04bb6e10cd Add a mmap flag (MAP_32BIT) on 64-bit platforms to request that a mapping use
an address in the first 2GB of the process's address space.  This flag should
have the same semantics as the same flag on Linux.

To facilitate this, add a new parameter to vm_map_find() that specifies an
optional maximum virtual address.  While here, fix several callers of
vm_map_find() to use a VMFS_* constant for the findspace argument instead of
TRUE and FALSE.

46d2ccf617 Make the primary name of the OF console device /dev/ofwcons, and only
alias it to the contents of the output property if it is defined. This
avoids a panic when booting machines (QEMU) where the output-device
property is not defined.

Since output-device is free-form and potentially conflicts with other
entries in /dev, I also am not sure we should be doing the aliasing at
all, but this at least makes things work again.

42ac52f951 Bring in some behind-the-scenes development, mainly By Arthur Mesh,
the rest by me.

o Namespace cleanup; the Yarrow name is now restricted to where it
  really applies; this is in anticipation of being augmented or
  replaced by Fortuna in the future. Fortuna is mentioned, but behind
  #if logic, and is ignorable for now.

o The harvest queue is pulled out into its own modules.

o Entropy harvesting is emproved, both by being made more conservative,
  and by separating (a bit!) the sources. Available entropy crumbs are
  marginally improved.

o Selection of sources is made clearer. With recent revelations,
  this will receive more work in the weeks and months to come.
