Additionally make bias and drive strength optional rather than required; not
setting them should just indicate that we do not need to configure these

SPDB was cleaned using TAILQ_CONCAT() instead of calling key_unlink()
for each SP, thus we need to properly clean lists in each bucket of
V_sphashtbl to avoid panic in hashdestroy() when INVARIANTS is enabled.
Do the same for V_acqaddrhashtbl and V_acqseqhashtbl.
When we are called in DEFAULT_VNET, destroy also all global locks and
drain key_timer callout.

We periodically record synchronization progress in the metadata
block of the disk being synchronized; this allows an interrupted
synchronization to be resumed. However, the frequency of these
updates heavily pessimized synchronization time on some media. This
change modifies gmirror to update metadata based on a time period,
and adds a sysctl to control that period. The default value results
in a much lower update frequency and increases the completion time
for an interrupted rebuild only marginally.

This change adds an implementation of a sysent for running CloudABI
armv6 and armv7 binaries on FreeBSD/arm64. It is a somewhat literal copy
of the armv6 version, except that it's been patched up to use the proper
registers.
Just like for cloudabi32.ko on FreeBSD/amd64, we make use of a vDSO that
automatically pads system call parameters to 64-bit value. These are
stored in a buffer on the stack, meaning we need to use copyin() and
copyout() unconditionally.
"panic: vdev_geom_close_locked: cp->private is NULL"
This panic will result if ZFS fails to open a device due to either of the
following reasons:
1) The device's sector size is greater than 8KB.
2) ZFS wants to open the device RW, but it can't be opened for writing.
The solution is to change the initialization order to ensure that the
assertion will be satisfied.

turn it off by default. It is very inefficient to verify current P-state of

requested to the same power domain before completion of pending transitions,
the last command is executed according to the manual. Because requests are

the caller does it anyway.

setrunnable()->sched_wakeup()->sched_add()
In r326218 code was added to allow booting from non-zero CPU numbers
by setting the ts_cpu field inside the ULE scheduler's sched_add()
function. This had an undesired side-effect that prior sched_pin() and
sched_bind() calls got disregarded. This patch fixes the
initialization of the ts_cpu field for the ULE scheduler to only
happen once when the initial thread is constructed during system
init. Forking will then later on ensure that a valid ts_cpu value gets
copied to all children.

Driver support is only provided for ConnectX4/5.
System-time timestamp is calculated based on the free-running counter
timestamp provided by hardware. Driver periodically samples the
counter to calibrate it against the system clock and uses linear
interpolation to convert. Stability of the crystal which drives the
clock is +-50 ppm at the operational temperature, which makes the
algorithm good enough.
The calculation is somewhat delicate because all values are 64bit and
overflow the naive formula for linear interpolation. The calculation
drops the least significant bits in advance, see the PREC shift in
mlx5_mbuf_tstmp().
Hardware stamps can be turned off by 'ifconfig mceN -hwrxtsmp'. Buggy
firmware might result in small but visible errors in the reported
timestamps, detectable e.g. by nonsensical (negative) RTT values for
LAN pings.

The arena argument to kmem_*() is now only used in an assert. A follow-up
commit will remove the argument altogether before we freeze the API for the
next release.
This replaces the hard limit on kmem size with a soft limit imposed by UMA. When
the soft limit is exceeded we periodically wakeup the UMA reclaim thread to
attempt to shrink KVA. On 32bit architectures this should behave much more
gracefully as we exhaust KVA. On 64bit the limits are likely never hit.

Very early BHND Wi-Fi devices (e.g. BCM4318) do not support any form of

Very early (PCI_V0) Broadcom PCI Wi-Fi chipsets have a few quirks when
compared to later PCI(e) core revisions:
- The standard static BAR0 mapping of the PCI core registers is discontiguous,
with siba's cfg0 register block mapped distinctly from the other core
registers.
- No dedicated ChipCommon register mapping is provided; instead, the
single configurable register window must be used to access both
ChipCommon and D11 core registers. The D11 core's operational semantics
guarantee the safety of -- after disabling interrupts -- borrowing
the single dynamic register window to perform the few ChipCommon
operations required by a driver.
To support these early PCI devices:
- Allow defining multiple discontiguous BHNDB_REGWIN_T_CORE register
windows that map a single port/region, and producing bridged resource
allocations backed by those discontiguous windows.
- Support stealing existing register window allocations to fulfill indirect
bhnd(4) bus I/O requests within address ranges tagged with
BHNDB_ALLOC_FULFILL_ON_OVERCOMMIT.
- Fix an inverted test of bhndb_is_pcie_attached() that disabled
PCI-only clock bring-up required by these devices.
