f6b84910bb Further rework netinet6 address handling code:
* 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.

b5a9d8b5a7 Enable vt. This brings VGA-based console and terminal support to
ia64 for the very first time. Only 9 years in the making...

Note that the vt/vga driver does not actually make sure there's
VGA hardware at the standard/legacy VGA I/O port and memory I/O
addresses. This can cause machine checks if the H/W does not have
a VGA controller.

9db69902c6 If the flowid is available for the mbuf that finalised the creation
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.)

95fbe4d0cc Simplify filling sockaddr_dl structure for if_resolvemulti()
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).

48b2d828a2 Some processor's don't allow NMI injection if the STI_BLOCKING bit is set in
the Guest Interruptibility-state field. However, there isn't any way to
figure out which processors have this requirement.

So, inject a pending NMI only if NMI_BLOCKING, MOVSS_BLOCKING, STI_BLOCKING
are all clear. If any of these bits are set then enable "NMI window exiting"
and inject the NMI in the VM-exit handler.

86fa24710e Style changes in vm_pageout_scan():
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.

6d03ca5789 traverse_visitbp: visit DMU_GROUPUSED_OBJECT before DMU_USERUSED_OBJECT
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.

0cfea1c8fc Implement a kqueue notification path for sendfile.
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.

2b80a75654 Implement the extension api for sendfile to allow for kqueue notifications.
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.)

160471d264 If a VM-exit happens during an NMI injection then clear the "NMI Blocking" bit
in the Guest Interruptibility-state VMCS field.

If we fail to do this then a subsequent VM-entry will fail because it is an
error to inject an NMI into the guest while "NMI Blocking" is turned on. This
is described in "Checks on Guest Non-Register State" in the Intel SDM.

- Add a release-dvd.conf pkg(8) configuration file to override
   the default FreeBSD.conf configuration.
 - Remove architecture-specific pkg-stage.conf files, consolidate,
   and move their contents to scripts/pkg-stage.sh.
 - Use 'pkg -vv' to determine the ABI, which is used as the
   cache directory.

Prior to these changes, it would be possible for pkg-stage to fetch
conflicting binary packages from multiple repositories.

876fa2c17b fix a bug in ZFS mirror code for handling multiple DVAa
The bug was introduced in r256956 "Improve ZFS N-way mirror read
performance".
The code in vdev_mirror_dva_select erroneously considers already
tried DVAs for the next attempt.  Thus, it is possible that a failing DVA
would be retried forever.
As a secondary effect, if the attempts fail with checksum error, then
checksum error reports are accumulated until the original request
ultimately fails or succeeds.  But because retrying is going on indefinitely
the cheksum reports accumulation will effectively be a memory leak.
