Strict value checking will cause problem.
Bay trail DN2820FYKH is supported on Linux but does not work on FreeBSD.
This behaviour is bug-compatible with Linux-3.13.5.

  ffec: Fix multicast filtering.

  Allwinner a10/a20...
  - Add gpio and clock bits for A10/A20's EMAC ethernet controller driver
    - EMAC gpio configuration
    - EMAC clock activation
  - Add Static Random Access Memory controller driver for A10/A20.
      A10/A20's SRAM is used by devices, such as CPU, EMAC,
      for extra fast memory or as cache.
  - Add EMAC 10/100 Ethernet controller driver for A10/A20.
      It is available mostly in A10 devices like Hackberry, Marsboard,
      Mele A1000, A2000, A100 HTPC, cubieboard1 and A20 device
      like cubieboard2.
      TX performance can be improved using both channels 0 and 1.
      RX performance is poor and needs improvement with the assistance of
      external DMA controller in case there
  - Add EMAC and SRAM controller entries to FDT.
  - Add EMAC device to kernel config files and enable EMAC, SRAM drivers.

  OMAP: When calculating the MPU freq, make sure not to overflow.

  Vybrid:
  - Add driver for Port control and interrupts (PORT).
  - Export panel info to DTS
  - Reset all the layers before setup first one
  - Enable display

  nandfs: Slight code reordering to make error branch last.

  Add option TMPFS to arm/conf/DEFAULTS, remove it from the few configs
  that have it individually.  Concensus on freebsd-arm@ is that it should
  be included in all ARM kernels.

  Fix the arm sys_sigreturn(): its argument is a struct ucontext, not a
  struct sigframe containing the struct ucontext.

Add a SUBDIR_PARALLEL option to bsd.subdir.mk, to allow make to process
all the SUBDIR entries in parallel, instead of serially.  Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.

This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.

I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

		before    stddev       after    stddev
		=======   ======       =======  ======
real time        1741.1     16.5         959.8     2.7
user time       12468.7     16.4       14393.0    16.8
sys  time        1825.0     54.8        2110.6    22.8

(user+sys)/real     8.2                   17.1

E.g. the build was approximately 45% faster in real time.  On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive.  But at least you can now almost max out a machine with
buildworld!

Once pf became not covered by a single mutex, many counters in it became

  A real problem was the race provoked underflow of the states_cur counter
  on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this
  value is used in pf_state_expires() and any state created by this rule
  is immediately expired.

  Thus, make fields states_cur, states_tot and src_nodes of struct
  pf_rule be counter(9)s.

        the kernel emits a resource.fs.zfs.statechange event for every vdev

        for every event.  The number of lines actually logged is reduced by

Correct alignment.

r259191:

For memsync replication, hio_countdown is used not only as an
indication when a request can be moved to done queue, but also for
detecting the current state of memsync request.

This approach has problems, e.g. leaking a request if memsynk ack from
the secondary failed, or racy usage of write_complete, which should be
called only once per write request, but for memsync can be entered by
local_send_thread and ggate_send_thread simultaneously.

So the following approach is implemented instead:

1) Use hio_countdown only for counting components we waiting to
   complete, i.e. initially it is always 2 for any replication mode.

2) To distinguish between "memsync ack" and "memsync fin" responses
   from the secondary, add and use hio_memsyncacked field.

3) write_complete() in component threads is called only before
   releasing hio_countdown (i.e. before the hio may be returned to the
   done queue).

4) Add and use hio_writecount refcounter to detect when
   write_complete() can be called in memsync case.

representation of the LUN is identical with and without PIM_EXTLUNS. Thus
setting PIM_EXTLUNS keeps most behavior, and user-facing LUN IDs, unchanged.
This follows the strategy used in Solaris. A macro (CAM_EXTLUN_BYTE_SWIZZLE)
is provided to transform a lun_id_t into a uint64_t ordered for the wire.

This is the second part of work for full 64-bit extended LUN support and is
designed to a bridge for stable/10 to the final 64-bit LUN code. The
third and final part will involve widening lun_id_t to 64 bits and will
not be MFCed. This third part will break the KBI but will keep the KPI
unchanged so that all drivers that will care about this can be updated now
and not require code changes between HEAD and stable/10.

  Currently, we've got a problem that interface isn't IFF_UP at the time
  we assign it a redundant address, and the latter gets stuck in INIT state.
  Additional SIOCSIFFLAGS from ifconfig(8) kicks it to a working state.

  A proper fix is kernel side and appeared to be non-trivial, not to be

5ea0541321 When updating the map of dirty extents, most recently used extents are
kept dirty to reduce the number of on-disk metadata updates. The
sequence of operations is:

1) acquire the activemap lock;
2) update in-memory map;
3) if the list of keepdirty extents is changed, update on-disk metadata;
4) release the lock.

On-disk updates are not frequent in comparison with in-memory updates,
while require much more time. So situations are possible when one
thread is updating on-disk metadata and another one is waiting for the
activemap lock just to update the in-memory map.

Improve this by introducing additional, on-disk map lock: when
in-memory map is updated and it is detected that the on-disk map needs
update too, the on-disk map lock is acquired and the on-memory lock is
released before flushing the map.

2604d523b6 Use cv_broadcast() instead of cv_signal() when waking up threads
waiting on an empty queue as the queue may have several consumers.

Before the fix the following scenario was possible: 2 threads are
waiting on empty queue, 2 threads are inserting simultaneously. The
first inserting thread detects that the queue is empty and is going to
send the signal, but before it sends the second thread inserts
too. When the first sends the signal only one of the waiting threads
receive it while the other one may wait forever.

The scenario above is is believed to be the cause of the observed
cases, when ggate_recv_thread() was getting stuck on taking free
request, while the free queue was not empty.

029a6f5d92 Change the cap_rights_t type from uint64_t to a structure that we can extend
in the future in a backward compatible (API and ABI) way.

The cap_rights_t represents capability rights. We used to use one bit to
represent one right, but we are running out of spare bits. Currently the new
structure provides place for 114 rights (so 50 more than the previous
cap_rights_t), but it is possible to grow the structure to hold at least 285
rights, although we can make it even larger if 285 rights won't be enough.

The structure definition looks like this:

	struct cap_rights {
		uint64_t	cr_rights[CAP_RIGHTS_VERSION + 2];
	};

The initial CAP_RIGHTS_VERSION is 0.

The top two bits in the first element of the cr_rights[] array contain total
number of elements in the array - 2. This means if those two bits are equal to
0, we have 2 array elements.

The top two bits in all remaining array elements should be 0.
The next five bits in all array elements contain array index. Only one bit is
used and bit position in this five-bits range defines array index. This means
there can be at most five array elements in the future.

To define new right the CAPRIGHT() macro must be used. The macro takes two
arguments - an array index and a bit to set, eg.

	#define	CAP_PDKILL	CAPRIGHT(1, 0x0000000000000800ULL)

We still support aliases that combine few rights, but the rights have to belong
to the same array element, eg:

	#define	CAP_LOOKUP	CAPRIGHT(0, 0x0000000000000400ULL)
	#define	CAP_FCHMOD	CAPRIGHT(0, 0x0000000000002000ULL)

	#define	CAP_FCHMODAT	(CAP_FCHMOD | CAP_LOOKUP)

There is new API to manage the new cap_rights_t structure:

	cap_rights_t *cap_rights_init(cap_rights_t *rights, ...);
	void cap_rights_set(cap_rights_t *rights, ...);
	void cap_rights_clear(cap_rights_t *rights, ...);
	bool cap_rights_is_set(const cap_rights_t *rights, ...);

	bool cap_rights_is_valid(const cap_rights_t *rights);
	void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src);
	void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src);
	bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little);

Capability rights to the cap_rights_init(), cap_rights_set(),
cap_rights_clear() and cap_rights_is_set() functions are provided by
separating them with commas, eg:

	cap_rights_t rights;

	cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT);

There is no need to terminate the list of rights, as those functions are
actually macros that take care of the termination, eg:

	#define	cap_rights_set(rights, ...)				\
		__cap_rights_set((rights), __VA_ARGS__, 0ULL)
	void __cap_rights_set(cap_rights_t *rights, ...);

Thanks to using one bit as an array index we can assert in those functions that
there are no two rights belonging to different array elements provided
together. For example this is illegal and will be detected, because CAP_LOOKUP
belongs to element 0 and CAP_PDKILL to element 1:

	cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL);

Providing several rights that belongs to the same array's element this way is
correct, but is not advised. It should only be used for aliases definition.

This commit also breaks compatibility with some existing Capsicum system calls,
but I see no other way to do that. This should be fine as Capsicum is still
experimental and this change is not going to 9.x.

9f2f2e171a Change <sys/diskpc98.h> to not redefine the same symbols that are
being defined in <sys/diskmbr.h>. Instead give the symbols here a
"PC98_" prefix. This way, both <sys/diskmbr.h> and <sys/diskpc98.h>
can be included in the same C source file.

The renaming is trivial. The only gotcha is that DOSBBSECTOR is
also redefined from 0 to 1. This because DOSBBSECTOR was always
used in conjunction with an addition of 1. The PC98_BBSECTOR symbol
is defined as 1 and the expression is simplified.

Note: it is not believed that ports are seriously impacted; or at
all for that matter.
