- there is a local variable for sc->fw_dma, use that instead
- OpenBSD uses 5*hz to wait for firmware to be loaded
- in case the firmware module contains invalid data, actually release it
- use ATA_SE_EXCHANGED (SError.DIAG.X) bit to detect hot-plug events when
power-management enabled and ATA_SE_PHY_CHANGED (SError.DIAG.N) can't be
trusted;
- on controllers supporting staggered spin-up (SS) put unused channels
into Listen state instead of Off. It should still save some power, but
allow plug-in events to be detected;
- on controllers supporting cold presence detection (CPD), when power
management enabled, use CPD events to detect hot-plug in addition to PHY
events.
down. The ingress queue lock was unused and has been removed as part of
these changes.
- An in-flight egress update from the SGE must be handled before the
queue that requested it is destroyed. Wait for the update to arrive.
- Interrupt handlers must stop processing rx events for a queue before
the queue is destroyed. Events that have not yet been processed
should be ignored once the queue disappears.

to determine if a file system supports NFSv4 ACLs. Since
VOP_PATHCONF() must be called with a locked vnode, the function
is called before nfsvno_fillattr() and the result is passed in
as an extra argument.

crossing of server mount points properly. The functions
nfsvno_fillattr() and nfsv4_fillattr() were modified to
take the extra arguments that are the mount point, a flag
to indicate that it is a file system root and the mounted
on fileno. The mount point argument needs to be busy when
nfsvno_fillattr() is called, since the vp argument is not
locked.

invariant and APERF/MPERF MSRs exist but these MSRs never tick. When we
calculate effective frequency from cpu_est_clockrate(), it caused panic of
division-by-zero. Now we test whether these MSRs actually increase to avoid
such foot-shooting.

ieee80211_chan2ieee() does return an ic_ieee as an int, but I heavily

unused upper 32 bits even when it is casted to a 32-bit value. It reduces
such compiler mistakes where every cycle counts.
Instead of spinning in a tight loop for up to 15 seconds, polling for device
readiness while it spins up, return reset completion just after PHY reports
"connect well" or 100ms connection timeout. If device was found, use callout
for checking device readiness with 100ms period up to full 31 second timeout.
This fixes system freeze for 5-10 seconds on drives hot plug-in.

Also, try harder to make sure that the fsid is different than
the one assigned to the client mount point, by hashing the
server's fsid (just to create a different value deterministically)
when it is the same.

details of each rman header, but not the contents of all rman structures
in the system. This is especially useful on platforms where some rmans
have many thousands of entries in rmans, making scrolling through the
output of "show all rman" impractical. Individual rmans can then be viewed
including their contents with "show rman 0xaddr" as usual.

This is bit dirty and likely should be revised at a later date,
with an eye to unifying/tidying up the whole diversity setup
and allowing developers to do "tricky stuff" as they desire.
For now, this works.
* add a new method, specifically for doing per-RX packet
antenna diversity
* set that HAL method only if it's Kite and a Kite chip that
does diversity.
* add a diversity flag to the HAL debugging section
* add a check to make sure the kite diversity code doesn't run
on boards that don't require it, as not all Kite chips will
implement it.
* add some debug statements when the diversity code makes
changes to the antenna diversity/combining setup.
