6703915ee7 adapt usb transfer code for SCHEDULER_STOPPED
When SCHEDULER_STOPPED() is true the mtx_owned() call may return
an unexpected and thus meaningless result.
So, in the code paths that can be reached when SCHEDULER_STOPPED() is true
we need to protect the mtx_owned() calls with the SCHEDULER_STOPPED()
checks and ensure that an appropriate branch is taken in each case.

713f46ac47 jwd@ reported a problem via email where the old NFS client would
get a reply of EEXIST from an NFS server when a Mkdir RPC was retried,
for an NFS over UDP mount.
Upon investigation, it was found that the client was retransmitting
the Mkdir RPC request over UDP, but with a different xid. As such,
the retransmitted message would miss the Duplicate Request Cache
in the server, causing it to reply EEXIST. The kernel client side
UDP rpc code has two timers. The first one causes a retransmit using
the same xid and socket and was set to a fixed value of 3seconds.
(The default can be overridden via CLSET_RETRY_TIMEOUT.)
The second one creates a new socket and xid and should be larger
than the first. However, both NFS clients were setting the second
timer to nm_timeo ("timeout=<value>" mount argument), which defaulted to
1second, so the first timer would never time out.
This patch fixes both NFS clients so that they set the first timer
using nm_timeo and makes the second timer larger than the first one.

971238ae48 The Xen pmap doesn't support superpages. So, there is no point in it
initializing structures, like the pv table, that are only used to
implement superpages.  In fact, some of the unnecessary code in
pmap_init() was actually doing harm.  It was preventing the kernel from
booting on virtual machines with more than 768 MB of memory.

f08535f872 Restore a feature that was present in 5.x and 6.x, and was cleared in
7.x, 8.x and 9.x with pf(4) imports: pfsync(4) should suppress CARP
preemption, while it is running its bulk update.

However, reimplement the feature in more elegant manner, that is
partially inspired by newer OpenBSD:

- Rename term "suppression" to "demotion", to match with OpenBSD.
- Keep a global demotion factor, that can be raised by several
  conditions, for now these are:
  - interface goes down
  - carp(4) has problems with ip_output() or ip6_output()
  - pfsync performs bulk update
- Unlike in OpenBSD the demotion factor isn't a counter, but
  is actual value added to advskew. The adjustment values for
  particular error conditions are also configurable, and their
  defaults are maximum advskew value, so a single failure bumps
  demotion to maximum. This is for POLA compatibility, and should
  satisfy most users.
- Demotion factor is a writable sysctl, so user can do
  foot shooting, if he desires to.

fd06fec782 IIC bitbang changes - prepare to make the bit delay configurable; debug print changes.
* Right now the delay is hard coded at 10uS. This is a bit long when doing lots
  of periodic i2c transactions. So create a 'udelay' parameter and initialise it
  to 10. This can be tuned later.

* Add a newline after a transaction finishes, so the debugging output isn't so

ddd7699151 Remove these locks - they aren't strictly needed and cause measurable
performance issues.

* Access to the GPIO bus is already locked by requesting
  and releasing the bus - thus the lock isn't really needed
  for each GPIO pin change.
* Don't lock and unlock the GPIO bus for -each- i2c access -
  the i2c bus code is already doing this by calling the upper
  layer callback to request/release the bus. This thus locks
  the bus for the entirety of the transaction.

TODO:

* Further verify that everything is correctly requesting/
  releasing the GPIO bus.
* Look at how to lock the GPIO pin configuration stuff,
  potentially by locking/unlocking the bus at the gpiobus
  layer.

167057914b ule: ensure that batch timeshare threads are scheduled fairly
With the previous code, if the range of priorities for timeshare batch
threads was greater than RQ_NQS, then the threads with low priorities in
the part of the range above RQ_NQS would be scheduled to the run-queues
as if they had high priorities at the beginning of the range.
In other words, threads with a nice level of +N could be scheduled as
if they had a nice level of -M.

cbecedb2c5 TCP header size is represented by number of 32bits words.
Fix the TCP header size calculation such that makes TSO engine
cache all header(ethernet/IP/TCP) bytes to its internal buffer.
While here, remove extra pull up for TCP payload.  Unlike some
em(4) controllers, fxp(4) does not require such work around for
TSO.
The two limitations are ethernet/IP/TCP header size should be less
than or equal to the size of controller's internal buffer(80 bytes)
and these header information should be found in the first fragment
of a TSO frame.
