19dfb7d609 Support watchdog depending on "mrvl,has-wdt" property
With this commit, watchdog is supported only in case of having
"mrvl,has-wdt" property or dedicated for watchdog compatibility field
("marvell,armada-380-wdt"). There is no need to modify dts files,
as "has-wdt" property already exists.

57f3351a9a Add support for watchdog on Armada38x
A38X watchdog support was implemented in sys/arm/mv/timer.c driver.
It required following modifications:
- add "marvell,armada-380-wdt" compatibility, which supports only watchdog
- correct and enhance definitions related to timer control register
- unmask reset capability in RSTOUTn_MASK register
- use dedicated watchdog timer on A38X instead of second timer

aae5878eb3 Initialize vm_page_prot to VM_MEMATTR_DEFAULT instead of 0.
If a driver's Linux mmap callback passed vm_page_prot through unchanged,
then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx
value 0 is to the mapping.  On x86, VM_MEMATTR_DEFAULT is the PAT value
for write-back (WB) which is 6, while 0 maps to the PAT value for
uncacheable (UC).  Thus, any mmap request that did not explicitly set
page_prot was tried to map memory as UC triggering the warning in
sg_pager_getpages().

Most likely, drivers for USB-serial-adapters likewise incorporating

897a9bc5d3 Various cleanups to the main function for AIO kernel processes:
- Pull the vmspace logic out into helper functions and reduce duplication.
  Operations on the vmspace are all isolated to vm_map.c, but it now exports
  a new 'vmspace_switch_aio' for use by AIO kernel processes.
- When an AIO kernel process wants to exit, break out of the main loop and
  perform cleanup after the loop end.  This reduces a lot of indentation and
  allows cleanup to more closely mirror setup actions before the loop starts.
- Convert a DIAGNOSTIC to KASSERT().
- Replace mycp with more typical 'p'.

5127f80e63 Disallow zvol-backed ZFS pools
Using zvols as backing devices for ZFS pools is fraught with panics and
deadlocks. For example, attempting to online a missing device in the
presence of a zvol can cause a panic when vdev_geom tastes the zvol.  Better
to completely disable vdev_geom from ever opening a zvol. The solution
relies on setting a thread-local variable during vdev_geom_open, and
returning EOPNOTSUPP during zvol_open if that thread-local variable is set.

Remove the check for MUTEX_HELD(&zfsdev_state_lock) in zvol_open. Its intent
was to prevent a recursive mutex acquisition panic. However, the new check
for the thread-local variable also fixes that problem.

Also, fix a panic in vdev_geom_taste_orphan. For an unknown reason, this
function was set to panic. But it can occur that a device disappears during
tasting, and it causes no problems to ignore this departure.

456370e530 Add optimizing LRO wrapper:
- Add optimizing LRO wrapper which pre-sorts all incoming packets
  according to the hash type and flowid. This prevents exhaustion of
  the LRO entries due to too many connections at the same time.
  Testing using a larger number of higher bandwidth TCP connections
  showed that the incoming ACK packet aggregation rate increased from
  ~1.3:1 to almost 3:1. Another test showed that for a number of TCP
  connections greater than 16 per hardware receive ring, where 8 TCP
  connections was the LRO active entry limit, there was a significant
  improvement in throughput due to being able to fully aggregate more
  than 8 TCP stream. For very few very high bandwidth TCP streams, the
  optimizing LRO wrapper will add CPU usage instead of reducing CPU
  usage. This is expected. Network drivers which want to use the
  optimizing LRO wrapper needs to call "tcp_lro_queue_mbuf()" instead
  of "tcp_lro_rx()" and "tcp_lro_flush_all()" instead of
  "tcp_lro_flush()". Further the LRO control structure must be
  initialized using "tcp_lro_init_args()" passing a non-zero number
  into the "lro_mbufs" argument.

- Make LRO statistics 64-bit. Previously 32-bit integers were used for
  statistics which can be prone to wrap-around. Fix this while at it
  and update all SYSCTL's which expose LRO statistics.

- Ensure all data is freed when destroying a LRO control structures,
  especially leftover LRO entries.

- Reduce number of memory allocations needed when setting up a LRO
  control structure by precomputing the total amount of memory needed.

- Add own memory allocation counter for LRO.

- Bump the FreeBSD version to force recompilation of all KLDs due to
  change of the LRO control structure size.

e6feb41fb0 sfxge: select whether to read current or backup partition in Medford A/B scheme
The dynamic config on Medford is stored using two partitions in flash, and at
any time one is the 'current' partition, used to provide the active config,
and the other 'backup' partition is used for writes.  This means that there
are two potential partitions that can be used to service reads, and which is
required can depend on, for example, whether the read is to get the current
contents or to verify a write.

When the partition write lock is held, the default behaviour is to read from
the backup partition, which was wrong for most reads in the common code which
require the current partition. This change allows the current partition to be
read whilst the write lock is held.
There is one read in Manftest which needs the backup partition.

ef10_nvram_partn_read_mode() is created to avoid changing
ef10_nvram_partn_read() which shares a prototype with the equivalent Falcon
and Siena methods.

MC_CMD_NVRAM_READ_IN_V2 adds an extra field, but firmware which doesn't support
it just ignores it.

cca6c88edd [iwm] fix up the rate control setup code to initialise rates in the order
we want to use it.

The rate table was being initialised in low->high, but the link quality
table was being initialised high->low. So, when we did a lookup, we
would get the indexes wrong.

This started by a patch from dragonflybsd which reversed how the ni->in_ridx[]
array is being used; I'd rather it all be consistent.  So, this is consistent.

9ab738affa Make PPS ASSERT/CLEAR events match the RS-232 signal levels as per RFC 2783.
Previously the polarity was for TTL levels, which are the reverse of RS-232.

Also add handling of the UART_PPS_INVERT_PULSE option bit in the sysctl
value, the same as was recently added to uart(4), so that people using TTL
level connections can request a logical inverting of the signal.

Use the named constants from the new dev/uart/uart_ppstypes.h for the pps
capture modes and option bits.

7d0828c94e When cleaning up from failed adv locking and checking for write, do
not call VOP_CLOSE() manually.  Instead, delegate the close to
fo_close() performed as part of the fdrop() on the file failed to
open.  For this, finish constructing file on error, in particular, set
f_vnode and f_ops.

Forcibly resetting f_ops to badfileops disabled additional cleanups
performed by fo_close() for some file types, in this case it was noted
that cdevpriv data was corrupted.  Since fo_close() call must be
enabled for some file types, it makes more sense to enable it for all
files opened through vn_open_cred().

533cb3d787 FAST_DEPEND: Fix incremental builds leading to kernel panics.
This fixes .depend.genassym.o not being included.  genassym.o depends on
all of the system headers and when rebuilt regenerates assym.s which
lists offsets for critial .S files to utilize.  By having a struct in a
system header change its offsets and not have generassym.o be rebuilt,
this would lead to panics.

The flaw in the initial commit was seeing ${OBJS} in ${SYSTEM_OBJS} and
assuming it had all of ${SRCS} in it.  This is not the case though.  The
older mkdep code splits out all of the various SRC lists for generating
the .depend file.  It also includes ${GEN_CFILES}, which had genassym.c
and was the only significant file lacking from ${SYSTEM_OBJS} upon inspection,
since it is not linked in.  Rather than duplicate the likely
soon-to-be-removed mkdep lists, just add genassym.o to the DEPENDOBJS
list.  Using ${SRCS} as bsd.dep.mk does would be nice but there are many
files in the build that are only added to ${OBJS} and not ${SRCS}, such
as bf_enc.o derived from bf_enc.S for i386.
