01a469b860 Add support for Allwinner H3 EMAC.
H3 EMAC is the same as A83T/A64 except the SoC includes an (optional)
internal 10/100 PHY. Both internal and external PHYs are supported on H3
with this driver.

86f1146329 Another issue reported on http://seclists.org/oss-sec/2016/q3/68 is
that struct kevent member ident has uintptr_t type, which is silently
truncated to int in the call to fget().  Explicitely check for the
valid range.

f470cca578 In ptrace_vm_entry(), do not call vmspace_free() while owning a vm
object lock.

The vmspace_free() operations might need to lock map, object etc on
last dereference.  Postpone the free until object's inspection is
done.

8d570f64aa Add a mask of optional ptrace() events.
ptrace() now stores a mask of optional events in p_ptevents.  Currently
this mask is a single integer, but it can be expanded into an array of
integers in the future.

Two new ptrace requests can be used to manipulate the event mask:
PT_GET_EVENT_MASK fetches the current event mask and PT_SET_EVENT_MASK
sets the current event mask.

The current set of events include:
- PTRACE_EXEC: trace calls to execve().
- PTRACE_SCE: trace system call entries.
- PTRACE_SCX: trace syscam call exits.
- PTRACE_FORK: trace forks and auto-attach to new child processes.
- PTRACE_LWP: trace LWP events.

The S_PT_SCX and S_PT_SCE events in the procfs p_stops flags have
been replaced by PTRACE_SCE and PTRACE_SCX.  PTRACE_FORK replaces
P_FOLLOW_FORK and PTRACE_LWP replaces P2_LWP_EVENTS.

The PT_FOLLOW_FORK and PT_LWP_EVENTS ptrace requests remain for
compatibility but now simply toggle corresponding flags in the
event mask.

While here, document that PT_SYSCALL, PT_TO_SCE, and PT_TO_SCX both
modify the event mask and continue the traced process.

d7e8cfd63d Do not allow creation of char or block special nodes with VNOVAL dev_t.
As was reported on http://seclists.org/oss-sec/2016/q3/68, tmpfs code
contains assertion that rdev != VNOVAL.  On FreeBSD, there is no other
consequences except triggering the assert.  To be compatible with
systems where device nodes have some significance, reject mknod(2)
call with dev == VNOVAL at the syscall level.

7ff1939db0 [ath] [ath_hal] break out the duration calculation to optionally include SIFS.
The pre-11n calculations include SIFS, but the 11n ones don't.

The reason is that (mostly) the 11n hardware is doing the SIFS calculation
for us but the pre-11n hardware isn't.  This means that we're over-shooting
the times in the duration field for non-11n frames on 11n hardware, which
is OK, if not a little inefficient.

Now, this is all fine for what the hardware needs for doing duration math
for ACK, RTS/CTS, frame length, etc, but it isn't useful for doing PHY
duration calculations.  Ie, given a frame to TX and its timestamp, what
would the end of the actual transmission time be; and similar for an
RX timestamp and figuring out its original length.

So, this adds a new field to the duration routines which requests
SIFS or no SIFS to be included.  All the callers currently will call
it requesting SIFS, so this /should/ be a glorious no-op.  I'm however
planning some future work around airtime fairness and positioning which
requires these routines to have SIFS be optional.

Notably though, the 11n version doesn't do any SIFS addition at the moment.
I'll go and tweak and verify all of the packet durations before I go and
flip that part on.

Tested:

* AR9330, STA mode
* AR9330, AP mode
* AR9380, STA mode
