52d7a117c0 Re-order the terms of an expression in arena_run_reg_dalloc() to correctly
detect whether the integer division table is large enough to handle the
divisor.  Before this change, the last two table elements were never used,
thus causing the slow path to be used for those divisors.

ab46d66ac3 In the case of POWERFAIL_NMI, remove the Giant acquisitions because they

3d06b4b330 Introduce some WITNESS improvements:
- Speedup the lock orderings lookup modifying the witness graph from a
  linked tree to a matrix. A table lookup caches the lock orderings in
  order to make a O(1) access for them. Any witness object has an unique
  index withing this lookup cache table.
- Reduce the lock contention on w_mtx acquiring it only when the LOR
  actually happens and not in a sane case. In order to do this don't totally
  flush lock lists (per-CPU spinlocks list and per-thread sleeplocks list)
  but check for ll_count anytime we need to have to verify allocations sanity.
- Introduce the function witness_thread_exit() in the witness namespace which
  should verify a thread doesn't hold any witness occurrence why exiting.
- Rename the sysctl debug.witness.graphs into debug.witness.fullgraph and
  add debug.witness.badstacks which prints out stacks for LOR revealed.
  This is implemented using the stack(9) support, which makes WITNESS to be
  dependent by the STACK option or by the DDB (including STACK) option.
- Fix style(9) for src/sys/kern/subr_witness.c

The hash table approach has been developed by Ilya Maykov on the behalf of
Isilon Systems which kindly released the patch.
Jeff Roberson, ported the patch to -CURRENT and fixed w_mtx contention, on the
behalf of Nokia.

8fced8fcdf Bump __FreeBSD_version to 800043, because of the bpf(4) change.
bpf(4) now uses cdevpriv to distinguish multiple file descriptors, where
it used to be implemented using device cloning. Ports like libpcap
properly detect the change in their configure scripts, but it doesn't
hurt to increase __FreeBSD_version.

While there, change the bpf(4) manual page to refer to /dev/bpf instead
of /dev/bpfN.

bc136b187d Attach the cpufreq child devices with specific orders to enforce relative
priority of some of the drivers that manage the same state (e.g. ichss0
vs est0).  Specifically, powernow, est, and p4tcc are added at order 10,
ichss at order 20, and smist at order 30.  Previously, some laptops were
seeing both ichss0 and est0 attaching and stomping on each other.

XXX: This isn't quite ideal, but works with the existing hacks, I think
what we really want instead is a single "speedstep0" device for CPUs
that the ichss, est, and smist drivers probe (but with differing
priorities).

136600fe59 Change bpf(4) to use the cdevpriv API.
Right now the bpf(4) driver uses the cloning API to generate /dev/bpf%u.
When an application such as tcpdump needs a BPF, it opens /dev/bpf0,
/dev/bpf1, etc. until it opens the first available device node. We used
this approach, because our devfs implementation didn't allow
per-descriptor data.

Now that we can, make it use devfs_get_cdevpriv() to obtain the private
data. To remain compatible with the existing implementation, add a
symlink from /dev/bpf0 to /dev/bpf. I've already changed libpcap to
compile with HAVE_CLONING_BPF, which makes it use /dev/bpf. There may be
other applications in the base system (dhclient) that use the loop to
obtain a valid bpf.

88abcb07bd Fix an interop issue with Linux: If you do nothing but TCP
mounts, Linux won't even bother registering nlockmgr for UDP. This
causes nlm_get_rpc to fail, which means any attempts to deliver the
GRANTED callback fail. Add code to nlm_get_rpc to try to locate the
TCP version as well. If it finds it on TCP, it establishes
a clnt_reconnect to the host.

94b9bedcb9 Fix compilation of arm's AVILA.
Compilation of the AVILA kernel failed because of two reasons:

- It needed curthread, which is defined through <sys/pcpu.h>.

- It still referred the softc's sc_mtx field, which has been replaced by
  sc_lock three weeks ago.

To solve the first problem, I decided to include <sys/pcpu.h> in
<sys/sx.h>, which also seems to be done by <sys/mutex.h> and
<sys/rwlock.h>. Those header files also require curthread.

ded7d39cb9 Reduce the scope of the vnode lock such that it does not cover
the various copyouts associated with initializing the process's
argv/env data in userspace.  It is possible that these copyout
operations can fault under memory pressure, possibly resulting
in dead locks.  This is believed to be safe since none of the
copyout_strings() operations need to interact with the vnode here.
