fa0bd53669 When sending export datagram from interrupt thread, use NG_QUEUE
in flags. When sending export datagram from expiry thread, then
use default zero flags. This removes unpleasant contention of the
interrupt thread on mutexes (usually ng_ksocket's socket buffer
mutex).

7f7a28fe5e * fix bst.status. We mark some bits, but forgot to reset all of them
before.  The symptom is that the battery inform us its charge and discharge
  at the same time...

* fix bst.rate to correctly output the (dis)charging rate.  We'll use
  the current average over one minute command and not the at_rate command.
  Note that this method is not correct if the capacity_mode is set, but
  since we don't set it ourself, it is not a problem.

  The at_rate do not give the actual rate but is used to compute the
  estimated time for (dis)charging a battery.  We should actually
  write an estimation of the actual rate using at_rate cmd and then
  perform a read to the various estimators.

a8f06e9570 In the splnet(9) times netgraph(4) was synchronous and if a message
had been replied, the reply was always delivered to the originator
synchronously.

With introduction of netgraph item callbacks and a wait channel with
mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning
earlier than the command has been proceeded by target node. But still
ngctl(8) can return prior to the reply has arrived to its node.

To fix this:
 - Introduce a new flag for netgraph(4) messages - NGM_HASREPLY.
   This flag is or'ed with message like NGM_READONLY.
 - In netgraph userland library if we have sent a message with
   NGM_HASREPLY flag, then select(2) until reply comes.
 - Mark appropriate generic commands with NGM_HASREPLY flag,
   gathering them into one enum {}. Bump generic cookie.

c40cc2b1b3 In moduledir_readhints() cast the value returned by sizeof() to ssize_t
when checking whether it's greater than a struct stat st_size in order
to also catch the case when st_size is -1. Previously this check didn't
trigger on sparc64 when st_size is -1 (as it's the case for a file on
a bzipfs, TFTP server etc.), causing the content of the linker hints
file to be copied to memory referenced by a null-pointer.

402d4e2682 - The inline asm in this file uses output operands before all input
operands are consumed so use the appropriate constraint modifier.
  Before this change GCC used one register for both an input and an
  unrelated output operand of in_addword(), causing the input to be
  overwritten before it was consumed and thus breaking in_addword().
  For in_cksum_hdr() and in_pseudo() this change is more or less
  cosmetic.

8872209c30 When deregistering a bus, attempt to flush out all outstanding
operations before returning. Point the bus at a dummy cam_sim
structure so that any CCBs will complete immediately with a
CAM_DEV_NOT_THERE status, and ensure that any xpt_schedule() calls
on the bus's devices will immediately call the peripheral's
periph_start() routine. Also repeat the async messages because
devices that were part of the way through being probed may appear
after the original AC_LOST_DEVICE was sent, and would otherwise
never go away.

These changes make it possible to deregister a bus and free the SIM
at most stages during bus probing without the usual crashes in
camisr(). In particular, plugging in a umass device and then
unplugging it as soon as the first probe messages appeared would
almost always result in a crash. Now the device just goes away with
a few CAM errors and all references to the CAM bus, target and
device are dropped correctly.

57bb282532 Significant performance improvements for the if_em driver:
- Only update the rx ring consumer pointer after running through the rx loop,
  not with each iteration through the loop.
- If possible, use a fast interupt handler instead of an ithread handler.  Use
  the interrupt handler to check and squelch the interrupt, then schedule a
  taskqueue to do the actual work.  This has three benefits:
  - Eliminates the 'interrupt aliasing' problem found in many chipsets by
    allowing the driver to mask the interrupt in the NIC instead of the
    OS masking the interrupt in the APIC.
  - Allows the driver to control the amount of work done in the interrupt
    handler.  This results in what I call 'adaptive polling', where you get
    the latency benefits of a quick response to interrupts with the
    interrupt mitigation and work partitioning of polling.  Polling is still
    an option in the driver, but I consider it orthogonal to this work.
  - Don't hold the driver lock in the RX handler.  The handler and all data
    associated is effectively serialized already.  This eliminates the cost of
    dropping and reaquiring the lock for every receieved packet.  The result
    is much lower contention for the driver lock, resulting in lower CPU usage
    and lower latency for interactive workloads.

The amount of work done in the taskqueue is controlled by the sysctl
dev.em.N.rx_processing_limit

and tunable
hw.em.rx_process_limit

Setting these to -1 effectively removes the limit.

The fast interrupt and taskqueue can be disabled by defining NO_EM_FASTINTR.
This work has been shown to increase fast-forwarding from ~570 kpps to
~750 kpps (note that the same NIC hardware seems unable to transmit more than
800 kpps, so this increase appears to be limited almost solely by the
hardware).  Gains have been shown in other workloads, ranging from better
performance to elimination of over-saturation livelocks.

Thanks to Andre Opperman for his time and resources from his network
performance project in performing much of the testing.  Thanks to Gleb
Smirnoff and Danny Braniss for their help in testing also.

706bc421be Add functions and macros and refactor code to make it easier to manage
fast taskqueues.  The following have been added:

TASKQUEUE_FAST_DEFINE() - create a global task queue.
    an arbitrary execution context.
TASKQUEUE_FAST_DEFINE_THREAD() - create a global taskqueue that uses a
    dedicated kthread.
taskqueue_create_fast() - create a local/private taskqueue.

These are all complimentary of the standard taskqueue functions.  They are
primarily useful for fast interrupt handlers that can only use spinlock for
synchronization.

I personally think that the taskqueue API is starting to get too narrow and
hairy, but fixing it will require a major redesign on the API.  Such a
redesign would be good but would break compatibility with FreeBSD 6.x, so
it really isn't desirable at this time.
