a1b7ff0a83 If opendir(".") fails after descending into a subdirectory via
chdir(), be sure to undo the effects of the chdir before continuing.

Without this, after hitting a directory with mode 0111 (for example),
tar will get lost, and won't add any yet unvisted files to your
archive.  (Or possibly add the wrong files, I suppose...)

1220194bac - Revert r1.406 until a solution can be found that doesn't break nfs. The
statfs handler in nfs will lock vnodes which may lead to deadlock or

5495fe549e - We can not hold a vnode lock while we do a lookup. Search for and load
modules prior to looking up the directory which we will cover to avoid
   this problem in mount.
 - We must hold the coveredvp locked before we can busy the mountpoint to
   prevent a lock order reversal with the vfs_busy() in lookup which holds
   the directory lock prior to doing a vfs_busy().  The directory lock is
   required to safely clear the v_mountedhere field on the directory.

d099befc57 - Grab a mnt ref in vfs_busy() before dropping the interlock. This will
prevent the mount point from going away while we're waiting on the lock.
   The ref does not need to persist once we have the lock because the
   lock prevents the mount point from being unmounted.

d08a9e33bf - spell VOP_LOCK(vp, LK_RELEASE... VOP_UNLOCK(vp,... so that asserts in
vop_lock_post do not trigger.
 - Rearrange null_inactive to null_hashrem earlier so there is no chance
   of finding the null node on the hash list after the locks have been
   switched.
 - We should never have a NULL lowervp in null_reclaim() so there is
   no need to handle this situation.  panic instead.

79ca2be05c - Assert that the lowervp is locked in null_hashget().
- Simplify the logic dealing with recycled vnodes in null_hashget() and
   null_hashins().  Since we hold the lower node locked in both cases
   the null node can not be undergoing recycling unless reclaim somehow
   called null_nodeget().  The logic that was in place was not safe and
   was essentially dead code.

55b3bd61d2 Lock the vm_object while checking its type to see if it is a vnode-backed
object that requires Giant in vm_object_deallocate().  This is somewhat
hairy in that if we can't obtain Giant directly, we have to drop the
object lock, then lock Giant, then relock the object lock and verify that
we still need Giant.  If we don't (because the object changed to OBJT_DEAD
for example), then we drop Giant before continuing.

e9c312bcac Split calcru() back into a calcru1() function shared with calccru() and
a calcru() wrapper that passes a local rusage_ext on the stack that is
a snapshot to do the calculations on.  Now we can pass p->p_crux to
calcru1() in calccru() again which fixes the issues with runtime going
backwards messages when dead processes are harvested by init.

1e99c29ded - In the interrupt handler clear the interrupt source flags before
processing the interrupt events. If we clear them afterwards we
  can completely miss some events as the NIC can change the source
  flags while we're in the handler. In order to not get another
  interrupt while we're in ifp->if_input() with the driver lock
  dropped we now turn off NIC interrupts while in the interrupt
  handler. Previously this was meant to be achieved by clearing the
  interrupt source flags after processing the interrupt events but
  didn't really work as clearing these flags doesn't actually
  acknowledge and re-enable the events.
  This fixes the device timeouts seen with the VMware LANCE.
- Relax the watchdog timer somewhat; don't enable it until the last
  packet is enqueued and if there is a TX interrupt but there are
  still outstanding ones reload the timer.
