4c2c7b2c94 Make init(8) slightly more robust when /dev/console is missing.
If the environment doesn't offer a working /dev/console, the existing
version of init(8) will simply refuse running rc(8) scripts. This means
you'll only have a system running init(8) and nothing else.

Change the code to do the following:

- Open /dev/console like we used to do, but make it more robust to use
  O_NONBLOCK to prevent blocking on a carrier.
- If this fails, use /dev/null as stdin and /var/log/init.log as stdout
  and stderr.
- If even this fails, use /dev/null as stdin, stdout and stderr.

So why us this useful? Well, if you remove the `getpid() == 1' check in
main(), you can now use init(8) inside jails to properly execute rc(8).
It still requires some polishing, as existing tools assume init(8) has
PID 1.

Also it is now possible to use use init(8) on `headless' devices that
don't even have a serial boot console.

93bd0cdedd Hide stty(1) errors.
If rc(8) is executed without using a TTY, this error appears at the
beginning:

	stty: stdin isn't a terminal

Because this is to be expected and of course not harmful, it is better
to simply hide the error message.

4391754075 Update comments and CFLAGS in sys/conf/kern.mk, introduced in r221879,
to match reality: clang does _not_ disable SSE automatically when
-mno-mmx is used, you have to specify -mno-sse explicitly.

Note this was the case even before r232894, which only makes a change in
the 'positive' flag case; e.g. when you specify -msse, MMX gets enabled
too.

fd053fae73 Add kern.eventtimer.activetick tunable/sysctl, specifying whether each
hardclock() tick should be run on every active CPU, or on only one.

On my tests, avoiding extra interrupts because of this on 8-CPU Core i7
system with HZ=10000 saves about 2% of performance. At this moment option
implemented only for global timers, as reprogramming per-CPU timers is
too expensive now to be compensated by this benefit, especially since we
still have to regularly run hardclock() on at least one active CPU to
update system uptime. For global timer it is quite trivial: timer runs
always, but we just skip IPIs to other CPUs when possible.

Option is enabled by default now, keeping previous behavior, as periodic
hardclock() calls are still used at least to implement setitimer(2) with
ITIMER_VIRTUAL and ITIMER_PROF arguments. But since default schedulers don't
depend on it since r232917, we are much more free to experiment with it.

7295465e33 Rewrite thread CPU usage percentage math to not depend on periodic calls
with HZ rate through the sched_tick() calls from hardclock().

Potentially it can be used to improve precision, but now it is just minus
one more reason to call hardclock() for every HZ tick on every active CPU.
SCHED_4BSD never used sched_tick(), but keep it in place for now, as at
least SCHED_FBFS existing in patches out of the tree depends on it.

8a5350984f Fix link status handling on if_arge upon system boot to allow bootp/NFS to
function.

From the submitter:

This patch fixes an issue I encountered using an NFS root with an
ar71xx-based MikroTik RouterBoard 450G on -current where the kernel fails
to contact a DHCP/BOOTP server via if_arge when it otherwise should be able
to.  This may be the same issue that Monthadar Al Jaberi reported against
an RSPRO on 6 March, as the signature is the same:

%%%

DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
.
.
.
DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
arge0: initialization failed: no memory for rx buffers
DHCP/BOOTP timeout for server 255.255.255.255
arge0: initialization failed: no memory for rx buffers

%%%

The primary issue that I found is that the DHCP/BOOTP message that
bootpc_call() is sending never makes it onto the wire, which I believe is
due to the following:

- Last December, a change was made to the ifioctl that bootpc_call() uses
to adjust the netmask around the sosend().

- The new ioctl (SIOCAIFADDR) performs an if_init when invoked, whereas the
old one (SIOCSIFNETMASK) did not.

- if_arge maintains its own sense of link state in sc->arge_link_status.

- On a single-phy interface, sc->arge_link_status is initialized to 0 in
arge_init_locked().

- sc->arge_link_status remains 0 until a phy state change notification
causes arge_link_task to run, notice the link is up, and set it to 1.

- The inits caused by the ifioctls in bootpc_call are reinitializing the
interface, but not the phy, so sc->arge_link_status goes to 0 and remains
there.

- arge_start_locked() always sees sc->arge_link_status == 0 and returns
without queuing anything.

The attached patch changes arge_init_locked() such that in the single-phy
case, instead of initializing sc->arge_link_status to 0, it runs
arge_link_task() to set it according to the current phy state.  This change
has allowed my setup to mount an NFS root successfully.

eeaef4bae5 Correctly (I hope) deallocate the if_arge RX buffer ring on arge_stop().
I had some interesting hangs until I realised I should try flushing the
DDR FIFO register and lo and behold, hangs stopped occuring.

I've put in a few DDR flushes here and there in case people decide to
reuse some of these functions.  It's very very likely they're almost
all superflous.

To test:

* Connect to a network with a _lot_ of broadcast traffic
* Do this:
  # while true; do ifconfig arge0 down; ifconfig arge0 up; done

This fixes the mbuf exhaustion that has been reported when the interface
state flaps up/down.
