9888acd231 Rework r252313:
The filedesc lock may not be dropped unconditionally before exporting
fd to sbuf: fd might go away during execution.  While it is ok for
DTYPE_VNODE and DTYPE_FIFO because the export is from a vrefed vnode
here, for other types it is unsafe.

Instead, drop the lock in export_fd_to_sb(), after preparing data in
memory and before writing to sbuf.

069178c4c3 Make a pass over this page to correct and clarify a few things as well as
some general word-smithing.
- Don't claim that adaptive mutexes have a timeout (they don't).
- Don't treat pool mutexes as a separate primitive in a few places.
- Describe sleepable read-mostly locks as a separate lock type and add
  them to the various tables.
- Don't claim that sx locks are less efficient.  That hasn't been true in
  a few years now.
- Describe lockmanager locks next to sx locks since they are very similar
  in terms of rules, etc., and so that all the lock primitives are
  grouped together before the non-lock primitives.
- Similarly, move the section on Giant after the description of all the
  non-lock primitives to preserve grouping.
- Condition variables work on several types of locks, not just mutexes.
- Add a bit of language to compare/contrast condition variables with
  sleep/wakeup.
- Add a note about why pause(9) is unique.
- Add some language to define bounded vs unbounded sleeps and explain
  why they are treated separately (bounded sleeps only need CPU time
  to make forward progress).
- Don't state that using mtx_sleep() is a bad idea.  It is in fact rather
  necessary.
- Rework the interaction table a bit.  First, it did not include really
  include sleepable rmlocks and it left out lockmgr entirely.  To get
  things to fit, combine similar lock types into the same column / row,
  and explicitly state what "sleep" means.  The notes about recursion
  and lock order were also a bit banal (lock order is always important,
  not just in the few places annotated here), so remove them.  In
  particular, the lock order note would need to be on just about every
  cell.  If we want to document recursion I think a better approach
  would be a separate table summarizing the recursion rules for each
  lock as having too many notes clutters the table.
- Tweak the tables to use less indentation so everything still fits with
  the added columns.
- Correct a few cells in the context mode table.
- Use mdoc markup instead of explicit markup in a few places.

4b2a7a843c Correct a bug that prevented deadlkres from (almost) ever firing.
deadlkres was using a reversed test to check whether ticks had rolled over.
This meant that deadlkres could only fire after ticks had rolled over.
This test was actually unnecessary as deadlkres only ever took the
difference of ticks values which is safe even in the presence of ticks
rollover.  Remove the tests entirely.  Now deadlkres will properly fire
after a lock has been held after the timeout period.

abdbf599d1 Make sure all CPUID values are handled, instead of exiting the
bhyve process when an unhandled one is encountered.

Hide some additional capabilities from the guest (e.g. debug store).

This fixes the issue with FreeBSD 9.1 MP guests exiting the VM on
AP spinup (where CPUID is used when sync'ing the TSCs) and the
issue with the Java build where CPUIDs are issued from a guest
userspace.

e725dd5c1e - Add a general purpose resource allocator, vmem, from NetBSD. It was
originally inspired by the Solaris vmem detailed in the proceedings
   of usenix 2001.  The NetBSD version was heavily refactored for bugs
   and simplicity.
 - Use this resource allocator to allocate the buffer and transient maps.
   Buffer cache defrags are reduced by 25% when used by filesystems with
   mixed block sizes.  Ultimately this may permit dynamic buffer cache
   sizing on low KVA machines.

c1207dc20c Make detaching drivers from PCI devices more robust. While here, fix a
bug where a PCI device would be powered down if it failed to probe, but
not when its driver was detached (e.g. via kldunload).
- Add a new helper method resource_list_release_active() which forcefully
  releases any active resources of a specified type from a resource list.
- Add a bus_child_detached method for the PCI bus driver which forces any
  active resources to be released (and whines to the console if it finds
  any) and then powers the device down.
- Call pci_child_detached() if we fail to probe a device when a driver
  is kldloaded.  This isn't perfect but can avoid leaking resources
  from a probe() routine in the kldload case.

8a3748f531 - Add vnode-backed swap space specification support. This is enabled when
device names "md" or "md[0-9]*" and a "file" option are specified in
  /etc/fstab like this:

  md    none    swap    sw,file=/swap.bin       0       0

- Add GBDE/GELI encrypted swap space specification support, which
  rc.d/encswap supported.  The /etc/fstab lines are like the following:

  /dev/ada1p1.bde       none    swap    sw      0       0
  /dev/ada1p2.eli       none    swap    sw      0       0

  .eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.

  swapctl(8) can understand an encrypted device in the command line
  like this:

  # swapctl -a /dev/ada2p1.bde

- "-L" flag is added to support "late" option to defer swapon until
  rc.d/mountlate runs.

- rc.d script change:

    rc.d/encswap -> removed
    rc.d/addswap -> just display a warning message if $swapfile is defined
    rc.d/swap1 -> renamed to rc.d/swap
    rc.d/swaplate -> newly added to support "late" option

These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

c15f698fb4 Add firmware replacement and activation support to nvmecontrol(8) through
a new firmware command.

NVMe controllers may support up to 7 firmware slots for storing of
different firmware revisions.  This new firmware command supports
firmware replacement (i.e. firmware download) with or without immediate
activation, or activation of a previously stored firmware image.  It
also supports selection of the firmware slot during replacement
operations, using IDENTIFY information from the controller to
check that the specified slot is valid.

Newly activated firmware does not take effect until the new controller
reset, either via a reboot or separate 'nvmecontrol reset' command to the
same controller.
