Document newly added loader tunables "hw.acpi.install_interface" and
"hw.acpi.remove_interface".
Use fprintf(stderr) instead of gctl_error() to print a warning about too
big sector size. When gctl error is set gctl_has_param() always returns
'false', which prevents geli(8) from finding some arguments and also masks
an error, which is generates in such case.

Add a flag to the experimental NFSv4 client to indicate when
delegations are being returned for reasons other than a Recall.
Also, re-organize nfscl_recalldeleg() slightly, so that it leaves
clearing NMODIFIED to the ncl_flush() call and invalidates the
attribute cache after flushing. It is hoped that these changes
might fix the problem others have seen when using the NFSv4
client with delegations enabled, since I can't reliably reproduce
the problem. These changes only affect the client when doing NFSv4
mounts with delegations enabled.

If input parameter cpusetsize is zero, give userland size of cpuset mask
kernel is using.
Remove locking and unlock in pthread_mutex_destroy, because
it can not fix race condition in application code, as a result,
the problem described in PR threads/151767 is avoided.
Sync code with tzcode2010m

asctime.c:
* Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if
  asctime_r is called with a NULL struct tm pointer.  (Note that
  asctime_r is called by ctime_r and asctime; asctime is called by
  ctime.)

localtime.c:
* Set errno to EINVAL and return WRONG if time1 is called with a
  NULL struct tm pointer; avoid dereference if a NULL struct tm
  pointer is passed to timelocal, timegm, or timeoff.  (Note that
  time1 is called by mktime, timegm, and timeoff; mktime is called
  by timelocal.)
* more core-avoidance work
* Change to set timezone and altzone based on time types with
  greatest transition times (for the benefit of Asia/Seoul).

zic.8:
* Warning about case-sensitivity of names, but not of abbrevations

zic.c:
* Conditionally output extra types with most-recently-use offsets
  last (for use by systems with pre-2011 versions of localtime.c,
  helping to ensure that globals "altzone and "timezone" get set
  correctly).

The code has been running for nearly four weeks on my laptop running
FreeBSD 8.1 without a problem.

- Revert r214409.
- Use long word to figure out sizeof kernel cpuset, hope it works.
Check small set and reject it, this is how kernel did. Always use the
size kernel is using.

[1] According to the x86 architectural specifications, no virtual-to-
physical page mapping should span two or more MTRRs of different types.
Add a pmap function, pmap_demote_DMAP(), by which the MTRR module can
ensure that the direct map region doesn't have such a mapping.

[2] Fix a couple of nearby style errors in amd64_mrset().

[3] Re-enable the use of 1GB page mappings for implementing the direct
map.  (See also r197580 and r213897.)

Add BCM5717C 10/100/1000TX PHY id.
Add initial BCM5718 family support. The BCM5718 family includes
the dual port BCM5717 and BCM5718 devices which are intended for
mainstream workstation and entry-level server designs and
represents the twelfth generation of NetXtreme Ethernet controllers.
This family is the successor to the BCM5714/BCM5715 family and
supports IPv4/IPv6 checksum offloading, TSO, VLAN hardware tagging,
jumbo frames, MSI/MSIX, IOV, RSS and TSS.

This change set supports all hardware features except IOV and
RSS/TSS. Unlike its predecessors, only extended RX buffer
descriptors can be posted to the jumbo producer ring. Single RX
buffer descriptors for jumbo frame are not supported. RSS requires
a more substantial set of changes and will apply to a larger set
of NetXtreme devices so RSS/TSS multi-queue support will be
implemented in a future releases.

Special thanks to Broadcom who kindly sent a sample board to me
and to davidch who gave provided the initial support code.

Use ${PICFLAG} instead of -fpic.
Language cleanup.
Use shorten model name and add RTL8168, RTL8111 to the list of
supported device. re(4) had been supported all variants of RTL8168,
RTL8111 and RTL810x. I think this change will cover all controllers
supported by re(4).
