Introduce queue mutex to serialize access to CCB, device and periph queues.
That should allow periphs to avoid taking heavily congested SIM lock up to
the moment of actually submitting CCB to the SIM.

Also as side effect it should allow different SIMs sharing same queue to
have separate locks.  I am not sure such hardware really exists now, but
seems it was planned in existing CAM design.

Prepare to replace the buf splay with a trie:

 - Don't insert BKGRDMARKER bufs into the splay or dirty/clean buf lists.
   No consumers need to find them there and it complicates the tree.
   These flags are all FFS specific and could be moved out of the buf
   cache.
 - Use pbgetvp() and pbrelvp() to associate the background and journal
   bufs with the vp.  Not only is this much cheaper it makes more sense
   for these transient bufs.
 - Fix the assertions in pbget* and pbrel*.  It's not safe to check list
   pointers which were never initialized.  Use the BX flags instead.  We
   also check B_PAGING in reassignbuf() so this should cover all cases.

mqueue,ksem,shm: Fix race condition with setting UF_EXCLOSE.

POSIX mqueue, compatibility ksem and POSIX shm create a file descriptor that
has close-on-exec set. However, they do this incorrectly, leaving a window
where a thread may fork and exec while the flag has not been set yet. The
race is easily reproduced on a multicore system with one thread doing
shm_open and close and another thread doing posix_spawnp and waitpid.

Set UF_EXCLOSE via falloc()'s flags argument instead. This also simplifies
the code.

Use 4-byte padding for core dump notes on both 32 and 64bit archs.

Although native word padding (i.e. 8-byte on 64bit arch) looks to be
in agreement with standards, other parts of our code and other OSes
use 4-byte alignment.

This is not expected to change alignment for currently generated core
dump notes, as the notes look to consist of structures with sizes
multiple of 8 on 64-bit archs. But there are plans to add additional
notes, where 4-byte vs 8-byte alignment makes difference.

This uses vfork() for simple commands and command substitutions containing a
single simple command, invoking an external program under certain conditions
(no redirections or variable assignments, non-interactive shell, no job
control). These restrictions limit the amount of code executed in a vforked
child.

Various incarnations of this patch have been shown to bring performance
improvements:
http://lists.freebsd.org/pipermail/freebsd-hackers/2012-January/037581.html

drm: Right-shift I2C slave address before passing it to aux channel

In r249041, I2C slave addresses were left-shifted at creation time to
have the same behavior between i915 and radeon (not committed yet). This
change broke the aux channel. The user-visible change was that display
port on i915 didn't work anymore.

To fix this, we right-shift the address back to restore the original value.

Fix a potential socket leak in the NFS server.  If a client closes its
connection after it was accepted by the userland nfsd process but before
it was handled off to svc_vc_create() in the kernel, then svc_vc_create()
would see it as a new listen socket and try to listen on it leaving a
dangling reference to the socket.  Instead, check for disconnected sockets
and treat them like a connected socket.  The call to pru_getaddr() should
fail and cause svc_vc_create() to fail.  Note that we need to lock the
socket to get a consistent snapshot of so_state since there is a window
in soisdisconnected() where both flags are clear.

Merge from projects/counters: UMA_ZONE_PCPU zones.

  These zones have slab size == sizeof(struct pcpu), but request from VM
enough pages to fit (uk_slabsize * mp_ncpus). An item allocated from such
zone would have a separate twin for each CPU in the system, and these twins
are at a distance of sizeof(struct pcpu) from each other. This magic value
of distance would allow us to make some optimizations later.

  To address private item from a CPU simple arithmetics should be used:

  item = (type *)((char *)base + sizeof(struct pcpu) * curcpu)

  These arithmetics are available as zpcpu_get() macro in pcpu.h.

  To introduce non-page size slabs a new field had been added to uma_keg
uk_slabsize. This shifted some frequently used fields of uma_keg to the
fourth cache line on amd64. To mitigate this pessimization, uma_keg fields
were a bit rearranged and least frequently used uk_name and uk_link moved
down to the fourth cache line. All other fields, that are dereferenced
frequently fit into first three cache lines.

- In every occasion when a xfer is removed from a tlabel's list, reset

Since now we support 256 items per slab, we need more bits
for us_freecount.

This grows uma_slab_head on 32-bit arches, but growth isn't
significant. Taking kmem zones as example, only the 32 byte
zone is affected, ipers is reduced from 113 to 112.

Ensure make -j N universe works correctly, by checking for an up-to-date
make before starting the universe targets themselves.  Otherwise, all of
the targets would attempt to build make simultaneously, overwriting each
other's copies of the make object files and executable.  This could lead
to strange errors, for example when partially-written make executables
are invoked.

Also amend r216620, to make the rest of universe wait properly until the
upgrade_checks target is finished, by adding universe_${target}_prologue
to the .ORDER target.  Otherwise, make will be too smart for its own
good, and start building the universe targets simultaneously with the
prologues anyway.

Change certain heavily used network related mutexes and rwlocks to
reside on their own cache line to prevent false sharing with other
nearby structures, especially for those in the .bss segment.

NB: Those mutexes and rwlocks with variables next to them that get
changed on every invocation do not benefit from their own cache line.
Actually it may be net negative because two cache misses would be
incurred in those cases.

ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl()
doesn't copyout in this case.

To solve this issue a new struct zfs_iocparm_t is introduced consisting of:
- zfs_ioctl_version (future backwards compatibility purposes)
- user space pointer to zfs_cmd_t (copyin and copyout)
- size of zfs_cmd_t (verification purposes)

The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way
what makes porting of new changes easier and ensures correct behavior if
returning an error.

Add a callback to the ada(4) driver so that it knows when GEOM has released
references to it.

This is the functional equivalent to change r237518, which added this
functionality to the cd(4) and da(4) drivers.

This fix prevents a panic caused by GEOM calling adaopen() while the device
is going away.  We now keep the device around until GEOM has finished
cleaning up its state.

ata_da.c:	In adaregister(), add a d_gone callback to the GEOM disk
		structure registered for the ada driver.  Increment the
		peripheral reference count for GEOM.

		Add a new callback, adadiskgonecb(), that GEOM calls when
		it is done with its resources.  This callback releases the
		reference acquired in adaregister().

Adjust the HMAC and CMAC functions to the FreeBSD environment
and include them into the kernel build in preparation for use
in the TCP-AO code.

Note that we do not have explicit_bzero() so the compiler may
optimize away the bzero() to wipe out key storage on the stack
before returning.

DTrace: option for time-ordered output

Merge changes from illumos:

3021 option for time-ordered output from dtrace(1M)
3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work
3025 register leak in D code generation
3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider

This brings yet another feature implemented in upstream DTrace.
A complete description is available here:
http://dtrace.org/blogs/ahl/2012/07/28/my-new-dtrace-favorite/

This change bumps the DT_VERS_* number to 1.9.1 in
accordance to what is done in illumos.

This change was somewhat complicated because upstream is mixed many
changes in an individual commit and some of the tests don't really
apply to us.

There are also appear to be differences in timestamping with Solaris
so we had to workaround some assertions making sure no regression
happened.

Special thanks to Fabian Keil for changes and testing.

Fix tcp_output() so that tcpcb is updated in the same manner when an
mbuf allocation fails, as in a case when ip_output() returns error.

To achieve that, move large block of code that updates tcpcb below
the out: label.

This fixes a panic, that requires the following sequence to happen:

1) The SYN was sent to the network, tp->snd_nxt = iss + 1, tp->snd_una = iss
2) The retransmit timeout happened for the SYN we had sent,
   tcp_timer_rexmt() sets tp->snd_nxt = tp->snd_una, and calls tcp_output().
   In tcp_output m_get() fails.
3) Later on the SYN|ACK for the SYN sent in step 1) came,
   tcp_input sets tp->snd_una += 1, which leads to
   tp->snd_una > tp->snd_nxt inconsistency, that later panics in
   socket buffer code.

For reference, this bug fixed in DragonflyBSD repo:

Fix bugs in the elapsed time calculation in ctlstat_standard()
pointed out by bde:

- Casting to long double isn't needed.
- The division isn't needed, multiplication can be used.
  "When 1 nanosecond is in a floating point literal, the whole
  expression is automatically promoted correctly."
- non-KNF indentation (1 tab) for the newly split line
- different non-KNF indentation (5 spaces) for the previously split
  line
- exessive parentheses around the division operation
- bogus blank line which splits up the etime initialization
- general verboseness from the above.
