41dcd4566c Mostly revert r203420, and add similar functionality into ada(4) since the
existing code caused problems with some SCSI controllers.

A new sysctl kern.cam.ada.spindown_shutdown has been added that controls
whether or not to spin-down disks when shutting down.
Spinning down the disks unloads/parks the heads - this is
much better than removing power when the disk is still
spinning because otherwise an Emergency Unload occurs which may cause damage
to the actuator.

588f6113eb Modify the experimental NFSv4 server's file handle hash function
to use the generic hash32_buf() function. Although adding the
bytes seemed sufficient for UFS and ZFS, since most of the bytes
are the same for file handles on the same volume, this might not
be sufficient for other file systems. Use of a generic function
also seems preferable to one specific to NFSv4.

5633f7ef7b The firmware does pad notifications to an even number of bytes (at least
the association notification), the included information though always
contains an elem block with an odd number of bytes. We handle the last
byte as if it might contain a whole elem block, this of course is not
true as one byte is not enough to hold a block, we therefore discard the
complete frame. The solution here is to subtract one from the actual
notification length, this is also what the Linux driver does. With this
change the frames ends exactly where the last elem block ends.

This commit also reverts r214160 which is no longer required and now even

abd7e035f4 Add workaround for BCM5906 A1 controller silicon bug. When
auto-negotiation results in half-duplex operation, excess collision
on the ethernet link may cause internal chip delays that may result
in subsequent valid frames being dropped due to insufficient
receive buffer resources. The workaround is to choose de-pipeline
method as a flow control decision for SDI. De-pipeline method
allows only 1 data in TxMbuf at a time such that a request to RDMA
from SDI is made only when TxMbuf is empty. Thanks for david for
providing detailed errata information.

a41cfdca06 - When disabling ktracing on a process, free any pending requests that
may be left.  This fixes a memory leak that can occur when tracing is
  disabled on a process via disabling tracing of a specific file (or if
  an I/O error occurs with the tracefile) if the process's next system
  call is exit().  The trace disabling code clears p_traceflag, so exit1()
  doesn't do any KTRACE-related cleanup leading to the leak.  I chose to
  make the free'ing of pending records synchronous rather than patching
  exit1().
- Move KTRACE-specific logic out of kern_(exec|exit|fork).c and into
  kern_ktrace.c instead.  Make ktrace_mtx private to kern_ktrace.c as a
  result.

d5e7511690 Bring in geli suspend/resume functionality (finally).
Before this change if you wanted to suspend your laptop and be sure that your
encryption keys are safe, you had to stop all processes that use file system
stored on encrypted device, unmount the file system and detach geli provider.

This isn't very handy. If you are a lucky user of a laptop where suspend/resume
actually works with FreeBSD (I'm not!) you most likely want to suspend your
laptop, because you don't want to start everything over again when you turn
your laptop back on.

And this is where geli suspend/resume steps in. When you execute:

	# geli suspend -a

geli will wait for all in-flight I/O requests, suspend new I/O requests, remove
all geli sensitive data from the kernel memory (like encryption keys) and will
wait for either 'geli resume' or 'geli detach'.

Now with no keys in memory you can suspend your laptop without stopping any
processes or unmounting any file systems.

When you resume your laptop you have to resume geli devices using 'geli resume'
command. You need to provide your passphrase, etc. again so the keys can be
restored and suspended I/O requests released.

Of course you need to remember that 'geli suspend' won't clear file system
cache and other places where data from your geli-encrypted file system might be
present. But to get rid of those stopping processes and unmounting file system
won't help either - you have to turn your laptop off. Be warned.

Also note, that suspending geli device which contains file system with geli
utility (or anything used by 'geli resume') is not very good idea, as you won't
be able to resume it - when you execute geli(8), the kernel will try to read it
and this read I/O request will be suspended.
