d2925cccc1 Introduce a cap_ioctl_t used for the 'cmds' arguments to cap_ioctls_limit() 
and cap_ioctls_get().  On FreeBSD, these are 'unsigned long', but on Linux,
ioctl(2) takes an 'int', making mild abstraction desirable.

ad7ea69dce Convert PTE eviction lock from an RW lock to a RM lock. It is held for 
writing approximately never (< 0.00000001% under heavy VM load, and it can
go for months without ever being acquired in normal operation). This
provides a 10% (2-minute) improvement in wall clock time for make -j32
buildworld on a 4-core 32-thread POWER8.

b12c0a9eeb 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.

c077e6287f 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.

97f2f66479 Remove unused upstream DTrace provider implementations that are duplicates 
of providers under sys/cddl/dev/. Also remove sdt_subr.c, which isn't used

fbe503d462 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.

daf63fd2f9 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.

3bd3e39e1a 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.

e2ad437112 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.)

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.
