IPv6. Initialize it only once in def_policy_init(). Remove its
initialization from key_init() and make it static.
Remove several fields from struct secpolicy:
* lock - it isn't so useful having mutex in the structure, but the only
thing we do with it is initialization and destroying.
* state - it has only two values - DEAD and ALIVE. Instead of take a lock
and change the state to DEAD, then take lock again in GC function and
delete policy from the chain - keep in the chain only ALIVE policies.
* scangen - it was used in GC function to protect from sending several
SADB_SPDEXPIRE messages for one SPD entry. Now we don't keep DEAD entries
in the chain and there is no need to have scangen variable.
Use TAILQ to implement SPD entries chain. Use rmlock to protect access
to SPD entries chain. Protect all SP lookup with RLOCK, and use WLOCK
when we are inserting (or removing) SP entry in the chain.
Instead of using pattern "LOCK(); refcnt++; UNLOCK();", use refcount(9)
API to implement refcounting in SPD. Merge code from key_delsp() and
_key_delsp() into _key_freesp(). And use KEY_FREESP() macro in all cases
when we want to release reference or just delete SP entry.

Fix the following issues:
- Removed revision from device softc, it isn't used anywhere else out of
device attach routine;
- Move the duplicated code for verification of valid banks (and pins) to
a single function;
- Use some macros to simplify the handling of some constants;
- Update some stale comments.
AR5416 and later NICs have more than 8 (Well, more than 6) GPIO pins.
So to support rfkill on these NICs we need to bump this up or the
rfkill GPIO pin may get reset to the wrong value.

According to objcopy(1) --target is for use where the input and output
formats are the same ("no translation"). In practice it does detect the
input format in any case, but be explicit that we're specifying the
output format as we are translating from ELF to EFI PE format.

deselect it after setting the block size. This is a similar bug that
was fixed elsewhere, but not here. This makes sure that we leave the
card deselected at the end of the loop, and we don't send any commands
to the card without it selected.

"hw.vmm.trace_guest_exceptions". To enable this feature set the tunable
to "1" before loading vmm.ko.
Tracing the guest exceptions can be useful when debugging guest triple faults.
Note that there is a performance impact when exception tracing is enabled
since every exception will now trigger a VM-exit.
Also, handle machine check exceptions that happen during guest execution
by vectoring to the host's machine check handler via "int $18".

output on every Nth call to the output routine. A sufficiently large N
effectively disables the animation completely.
Resizing a ZFS ZVOL with debug enabled would result in a panic due to
recursion on dp_config_rwlock.
The upstream change "3464 zfs synctask code needs restructuring" changed
zvol_set_volsize to avoid the recursion on dp_config_rwlock, but this was
missed when originally merged in by r248571 due to significant differences
in our codebases in this area.
These changes also relied on bring in changes from upstream:
3557 dumpvp_size is not updated correctly when a dump zvol's size is
changed, which where also not present.

Current VT drivers don't register the memory regions they use with the
nexus. This patch makes vt_vga and vt_efifb register the memory regions they
use.
This is needed (at least) for Xen support, since the FreeBSD kernel will try
to use the holes in the memory map to map memory from other domains and
setup it's grant table.
