Should have been part of r260889, but waasn't due to command line typo.

* Set ia address/mask values BEFORE attaching to address lists.
Inet6 address assignment is not atomic, so the simplest way to
do this atomically is to fill in ia before attach.
* Validate irfa->ia_addr field before use (we permit ANY sockaddr in old code).
* Do some renamings:
in6_ifinit -> in6_notify_ifa (interaction with other subsystems is here)
in6_setup_ifa -> in6_broadcast_ifa (LLE/Multicast/DaD code)
in6_ifaddloop -> nd6_add_ifa_lle
in6_ifremloop -> nd6_rem_ifa_lle
* Split working with LLE and route announce code for last two.
Add temporary in6_newaddrmsg() function to mimic current rtsock behaviour.
* Call device SIOCSIFADDR handler IFF we're adding first address.
In IPv4 we have to call it on every address change since ARP record
is installed by arp_ifinit() which is called by given handler.
IPv6 stack, on the opposite is responsible to call nd6_add_ifa_lle() so
there is no reason to call SIOCSIFADDR often.

of a syncache connection, copy it into the inp_flowid field.
Without this, an incoming TCP connection won't have an inp_flowid marked
until some data comes in, and this means that things like the per-CPU
TCP timer option will choose a different CPU for the timer work.
(It also means that if one grabbed the flowid via an ioctl from userland,
it won't be available until some data has been received.)

callback providers. link_init_sdl() function can be used to
fill most of the parameters. Use caller stack instead of
allocation / freing memory for each request. Do not drop support
for extra-long (probably non-existing) link-layer protocols by
introducing link_alloc_sdl() (used by if_resolvemulti() callback)
and link_free_sdl() (used by caller).
Since this change breaks KBI, MFC requires slightly different approach
(link_init_sdl() auto-allocating buffer if necessary to handle cases
with unmodified if_resolvemulti() callers).

So, inject a pending NMI only if NMI_BLOCKING, MOVSS_BLOCKING, STI_BLOCKING

and inject the NMI in the VM-exit handler.
1. Be consistent in the style of "act_delta" manipulations between the
inactive and active queue scans.
2. Explicitly compare to zero.
3. The deactivation of a page is based is based on its recent history
and not just the current call to vm_pageout_scan(). The variable
"act_delta" represents the current state of the page, and not its
history. Avoid possible confusion by not (ab)using "act_delta" for
the making the deactivation decision.

Among some of the objc changes from Apple that crept into r260311,
Radar 5355344 is incomplete and is not used since we don't carry

The dead code seems to have caused issues in some Tinderboxes so

This is done to ensure that visited object IDs are always increasing.
Also, pass correct object ID to prefetch_dnode_metadata for
os_groupused_dnode.
Without this change we would hit an assert if traversal was paused on
a GROUPUSED object, which is unlikely but possible.
Apparently the same change was independently developed by Deplhix.

This fires off a kqueue note (of type sendfile) to the configured kqfd
when the sendfile transaction has completed and the relevant memory
backing the transaction is no longer in use by this transaction.
This is analogous to SF_SYNC waiting for the mbufs to complete -
except now you don't have to wait.
Both SF_SYNC and SF_KQUEUE should work together, even if it
doesn't necessarily make any practical sense.
This is designed for use by applications which use backing cache/store
files (eg Varnish) or POSIX shared memory (not sure anything is using
it yet!) to know when a region of memory is free for re-use. Note
it doesn't mark the region as free overall - only free from this
transaction. The application developer still needs to track which
ranges are in the process of being recycled and wait until all
pending transactions are completed.

This is still under a bit of flux, as the final API hasn't been nailed
down. It's also unclear whether we should define the two new types in the
header or not - it may allow bad code to compile that shouldn't (ie,
since uintX's are defined, the developer may not include sys/types.h.)

If we fail to do this then a subsequent VM-entry will fail because it is an
