- Convert the testcases to ATF
- Do some style(9) cleanups:
-- Sort headers
-- Apply indentation fixes
-- Remove superfluous parentheses
- Explicitly print out debug printfs for use with `kyua {debug,report}`; for
items that were overly noisy, they've been put behind #ifdef DEBUG
conditionals
- Fix some format strings

to do is to clean up the timer handling using the async-drain.
Other optimizations may be coming to go with this. Whats here
will allow differnet tcp implementations (one included).

When a multipath member is orphaned its access members are zeroed before its
removed if marked for wither, so prevent any future calls to g_access on
such members.
This prevents a panic on debug kernels which validates the resultant values
aren't negative.

It may only be used with WITH_AUTO_OBJ, which the WITH_DIRDEPS_BUILD does. We
could support this in the normal build as well if we forced creating the directory
and setting .OBJDIR.

The intention was to just limit leading zeroes on numeric names. That
check is now improved to also catch the leading spaces and '+' that
strtoul can pass through.

(1) The pmap argument passed to the function must be current pmap only.
(2) The process must be single threaded as the function is called either
when a process is exiting or from exec_new_vmspace().
Remove pmap_tlb_flush_ng() which is not used anywhere now.

When using lagg failover mode neither Gratuitous ARP (IPv4) or Unsolicited
Neighbour Advertisements (IPv6) are sent to notify other nodes that the
address may have moved.
This results is slow failover, dropped packets and network outages for the
lagg interface when the primary link goes down.
We now use the new if_link_state_change_cond with the force param set to
allow lagg to force through link state changes and hence fire a
ifnet_link_event which are now monitored by rip and nd6.
Upon receiving these events each protocol trigger the relevant
notifications:
* inet4 => Gratuitous ARP
* inet6 => Unsolicited Neighbour Announce
This also fixes the carp IPv6 NA's that stopped working after r251584 which
added the ipv6_route__llma route.
The new behavour can be controlled using the sysctls:
* net.link.ether.inet.arp_on_link
* net.inet6.icmp6.nd6_on_link
Also removed unused param from lagg_port_state and added descriptions for the
sysctls while here.

in pmap_remove_pages().
Some points were considered:
(1) There is no range TLB flush cp15 function.
(2) There is no target selection for hardware TLB flush broadcasting.
(3) Some memory ranges could be mapped sparsely.
(4) Some memory ranges could be quite large.
Tested by buildworld on RPi2 and Jetson TK1, i.e. 4 core platforms.
It turned out that the buildworld time is faster. On the other hand,
when the postponed TLB flush was also removed from pmap_remove_pages(),
the result was worse. But pmap_remove_pages() is called for removing
all user mapping from a process, thus it's quite expected.
Note that the postponed TLB flushes came here from i386 pmap where
hardware TLB flush broadcasting is not available.

Add -N flag to reboot(8) which bypasses the userland sync(2) during
reboot(8) while still allow the kernel sync during the reboot(2) syscall
to occur.
An example use of this is when rebooting with disconnected iSCSI sessions
which would otherwise cause the reboot to hang on BIOs that will never
complete.

This fixes an issue observed on Cortex A7 (RPi2) and on Cortex A15
(Jetson TK1) causing various memory corruptions. It turned out that
even L2 page table with no valid mapping might be a subject of such
caching.
Note that not all platforms have intermediate TLB caching implemented.
An open question is if this fix is sufficient for all platforms with
this feature.

Without the patch, there is a race condition: when poll() is invoked(),
if kvp_globals.daemon_busy is false, the daemon won't be timely
woke up, because hv_kvp_send_msg_to_daemon() can't wake up the daemon
in this case.

Current code doesn't try to make use of the full page when bouncing because
the size is only expanded to be a multiple of the alignment. Instead try to
always create segments of PAGE_SIZE when using bounce pages.
This allows us to remove the specific casing done for
BUS_DMA_KEEP_PG_OFFSET, since the requirement is to make sure the offsets
into contiguous segments are aligned, and now this is done by default.

panics when unloading the dummynet and IPFW modules:
- The callout drain function can sleep and should not be called having
a non-sleepable lock locked. Remove locks around "ipfw_dyn_uninit(0)".
- Add a new "dn_gone" variable to prevent asynchronous restart of
dummynet callouts when unloading the dummynet kernel module.
- Call "dn_reschedule()" locked so that "dn_gone" can be set and
checked atomically with regard to starting a new callout.

This is a holdover from how reset is handled in the ARGE_MDIO world.
You need to define the mdio bus device if you want to use the ethernet
device or the arge setup path doesn't bring the MAC out of reset.
