f8dd61b4d9 - When VFS_VGET() is not supported, switch to VOP_LOOKUP().
- We are fine by only share-locking the vnode.
- Remove assertion that doesn't hold for ZFS where we cross mount points
  boundaries by going into .zfs/snapshot/<name>/.

2943e7b899 - Check the result of malloc(M_NOWAIT) in replay_alloc(). The caller
(replay_alloc()) knows how to handle replay_alloc() failure.
- Eliminate 'freed_one' variable, it is not needed - when no entry is found
  rce will be NULL.
- Add locking assertions where we expect a rc_lock to be held.

fbe278c343 Add an experimental feature to shadow video BIOS. Long ago, this trick was
supported by many BIOSes to improve performance of VESA BIOS calls for real
mode OSes but it is not our intention here.  However, this may help some
platforms where the video ROMs are inaccessible after suspend, for example.
Note it may consume up to 64K bytes of contiguous memory depending on video
controller model when it is enabled.  This feature can be disabled by
setting zero to 'debug.vesa.shadow_rom' loader tunable via loader(8) or
loader.conf(5).  The default is 1 (enabled), for now.

4db720c0be Intel QPI chipsets actually provide two extra "non-core" PCI buses that
provide PCI devices for various hardware such as memory controllers, etc.
These PCI buses are not enumerated via ACPI however.  Add qpi(4) psuedo
bus and Host-PCI bridge drivers to enumerate these buses.  Currently the
driver uses the CPU ID to determine the bridges' presence.

40ea18d207 Prodded by Yongari, add support for Holtek HT80232. Add the device
ID, plus the ability to force '16-bit mode' which really means NE-2000
mode.  Other open source drivers suggest that the Holtek misbehaves if
you allow the 8-bit probe.  Also, all of the PCI chips emulate
NE-2000ish cards, so always force 16-bit mode for memory transfers.

4d7ceccb99 If the first iteration of the do loop in replay_prune()
succeeded and a subsequent interation failed to find an
entry to prune, it could loop infinitely, since the
"freed" variable wasn't reset to FALSE. This patch moves
setting freed FALSE to inside the loop to fix the problem.
