a0f9ee9a86 Move special DDP handling for closing a connection into a new 
handle_ddp_close() function in t4_ddp.c as the logic is similar
to handle_ddp_data().  This allows all knowledge of the special
DDP mbufs to be private to t4_ddp.c as well.

af4c17529a Report ARAT (APIC-Timer-always-running) feature for virtual CPU. 
This makes FreeBSD guest to not avoid using LAPIC timer, preferring HPET
due to worries about non-existing for virtual CPUs deep sleep states.

Benchmarks of usleep(1) on guest and host show such extra latencies:
 - 51us for virtual HPET,
 - 22us for virtual LAPIC timer,
 - 22us for host HPET and
 - 3us for host LAPIC timer.

d854427d60 Remove unused upstream DTrace provider implementations that are duplicates 
of providers under sys/cddl/dev/. Also remove sdt_subr.c, which isn't used
in FreeBSD's SDT implementation.

8c033d13b5 proc: get rid of proc lock + unlock pair in proc_reap 
A comment in the code stated we PROC_LOCK and as a side effect guarantee
all writers released process lock. But at that point such lock was already
taken while we were removing the process from all lists, so it should be already
unreachable.

054f9cab59 cred: add proc_set_cred helper 
The goal here is to provide one place altering process credentials.

This eases debugging and opens up posibilities to do additional work when such
an action is performed.

af70fecfb9 Use ar71xx_mac_addr_random_init() instead of a hand-rolled random

74b6ad6fe4 Start fleshing out some MAC address helper functions. 
A lot of these embedded boards don't have a unique MAC address per
device stored somewhere unique - sometimes they'll have one MAC
for both arge NICs; someties they'll have one MAC for both arge NICs
/and/ the ath NICs.  In these instances, we need to derive device
specific MAC addresses from the base MAC address.

These functions will be used by some follow-up code that'll slot
into if_arge and if_ath.

88f71e0aa9 Add a new taskqueue (device specific, not net80211 ic->tq); use it for 
device restart.

(Committers note - once scan overhaul and a few other things have been
fixed in net80211 to not block things in the taskqueue, this can disappear
and the device specific taskqueues in other drivers can also go away.)

9376a63b82 Don't unlock mutex in interrupt thread (except for wpi_rx_done() - for now) - 
fixes various races between wpi_notif_intr() and wpi_stop_locked().

(attachment 154381)

Committers note: yes, unlock/if_input/lock has to go away, but that'll
have to be done later.
