229d894543 In pmap_set_pte(), make sure to enforce ordering by inserting a memory
fence. Under system load, the CPU has been found to change the order
by which the stores are made visible. When the tag is made visible
before the other TLB values, other CPUs may use the invalid TLB values
and do bad things.

While here (i.e. not a fix) don't return errors from pmap_remove_vhpt()
to callers of pmap_remove_pte(). Those callers don't check the return
value and as such don't do what is needed to keep a consistent state.
More importantly, pmap_remove_vhpt() can't really have an error without
it indicating something unintended. Using KASSERT is therefore better.

0894229871 Add a new flag to /etc/ttys: onifconsole. This is equivalent to "on" if the
device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line
by default without providing one on all systems by default.

c9341dd343 - Allow PCI devices that are attached to a driver to be identified by their
device name instead of just the selector.
- Accept an optional device argument to -l to restrict the output to only
  listing details about a single device.  This is mostly useful in
  conjunction with other flags like -e or -c to allow a user to query
  details about a single device.

d76a1ef4e1 Introduce grab and ungrab upcalls. When the kernel desires to grab the
console, it calls the grab functions. These functions should turn off
the RX interrupts, and any others that interfere. This makes mountroot
prompt work again. If there's more generalized need other than
prompting, many of these routines should be expanded to do those new
things.

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

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.
