ab83575070 Make CloudABI's way of doing TLS more friendly to userspace emulators.
We're currently seeing how hard it would be to run CloudABI binaries on
operating systems cannot be modified easily (Windows, Mac OS X). The
idea is that we want to just run them without any sandboxing. Now
that CloudABI executables are PIE, this is already a bit easier, but TLS
is still problematic:

- CloudABI executables want to write to the %fs, which typically
  requires extra system calls by the emulator every time it needs to
  switch between CloudABI's and its own TLS.

- If CloudABI executables overwrite the %fs base unconditionally, it
  also becomes harder for the emulator to store a backup of the old
  value of %fs. To solve this, let's no longer overwrite %fs, but just
  %fs:0.

As CloudABI's C library does not use a TCB, this space can now be used
by an emulator to keep track of its internal state. The executable can
now safely overwrite %fs:0, as long as it makes sure that the TCB is
copied over to the new TLS area.

Ensure that there is an initial TLS area set up when the process starts,
only containing a bogus TCB. We don't really care about its contents on
FreeBSD.

38526a2cf1 Sync in the latest CloudABI system call definitions.
Some time ago I made a change to merge together the memory scope
definitions used by mmap (MAP_{PRIVATE,SHARED}) and lock objects
(PTHREAD_PROCESS_{PRIVATE,SHARED}). Though that sounded pretty smart
back then, it's backfiring. In the case of mmap it's used with other
flags in a bitmask, but for locking it's an enumeration. As our plan is
to automatically generate bindings for other languages, that looks a bit
sloppy.

Change all of the locking functions to use separate flags instead.

1f3bbfd875 Replace the CloudABI system call table by a machine generated version.
The type definitions and constants that were used by COMPAT_CLOUDABI64
are a literal copy of some headers stored inside of CloudABI's C
library, cloudlibc. What is annoying is that we can't make use of
cloudlibc's system call list, as the format is completely different and
doesn't provide enough information. It had to be synced in manually.

We recently decided to solve this (and some other problems) by moving
the ABI definitions into a separate file:

	https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt

This file is processed by a pile of Python scripts to generate the
header files like before, documentation (markdown), but in our case more
importantly: a FreeBSD system call table.

This change discards the old files in sys/contrib/cloudabi and replaces
them by the latest copies, which requires some minor changes here and
there. Because cloudabi.txt also enforces consistent names of the system
call arguments, we have to patch up a small number of system call
implementations to use the new argument names.

The new header files can also be included directly in FreeBSD kernel
space without needing any includes/defines, so we can now remove
cloudabi_syscalldefs.h and cloudabi64_syscalldefs.h. Patch up the
sources to include the definitions directly from sys/contrib/cloudabi
instead.

0aeed3e993 Add support for the Freescale dTSEC DPAA-based ethernet controller.
Freescale's QorIQ line includes a new ethernet controller, based on their
Datapath Acceleration Architecture (DPAA).  This uses a combination of a Frame
manager, Buffer manager, and Queue manager to improve performance across all
interfaces by being able to pass data directly between hardware acceleration
interfaces.

As part of this import, Freescale's Netcomm Software (ncsw) driver is imported.
This was an attempt by Freescale to create an OS-agnostic sub-driver for
managing the hardware, using shims to interface to the OS-specific APIs.  This
work was abandoned, and Freescale's primary work is in the Linux driver (dual
BSD/GPL license).  Hence, this was imported directly to sys/contrib, rather than
going through the vendor area.  Going forward, FreeBSD-specific changes may be
made to the ncsw code, diverging from the upstream in potentially incompatible
ways.  An alternative could be to import the Linux driver itself, using the
linuxKPI layer, as that would maintain parity with the vendor-maintained driver.
However, the Linux driver has not been evaluated for reliability yet, and may
have issues with the import, whereas the ncsw-based driver in this commit was
completed by Semihalf 4 years ago, and is very stable.

Other SoC modules based on DPAA, which could be added in the future:
* Security and Encryption engine (SEC4.x, SEC5.x)
* RAID engine

Additional work to be done:
* Implement polling mode
* Test vlan support
* Add support for the Pattern Matching Engine, which can do regular expression
  matching on packets.

This driver has been tested on the P5020 QorIQ SoC.  Others listed in the
dtsec(4) manual page are expected to work as the same DPAA engine is included in
all.

ff066b54ec fix ht/40 configuration for ar9331 (hornet).
The synth programming here requires the real centre frequency,
which for HT20 channels is the normal channel, but HT40 is
/not/ the primary channel.  Everything else was using 'freq',
which is the correct centre frequency, but the hornet config
was using 'ichan' to do the lookup which was also the primary
channel.

So, modify the HAL call that does the mapping to take a frequency
in MHz and return the channel number.

Tested:

* Carambola 2, AR9331, tested both HT/20 and HT/40 operation.

27e2ad4687 Add initial support for the QCA953x SoC (honeybee) wifi.
This is a 2x2 2GHz 802.11n part.  It works enough at the moment to
bring up, scan and associate.  I haven't started using this as
a day to day AP.

The specifics:

* add honeybee initvals
* add in changes; a mix from the QCA HAL and ath9k;
* fix a bug in AR_SREV_AR9580_10_OR_LATER(), which is only used
  for one capability check and we don't even implement it - so it's
  a big no-op.

Shady things:

* ath9k has the "platform data" define the 25/40MHz clock.
  This HAL .. doesn't.  Honeybee gets hard-coded to 25MHz which
  it likely shouldn't be.  I'll have to go and identify/fix those.

Tested:

* Qualcomm Atheros AP143 reference design board.

f50e4ebf6a ath(4): begin fleshing out a "reset type" extension to force cold/warn resets.
Right now the only way to force a cold reset is:

* The HAL itself detects it's needed, or
* The sysctl, setting all resets to be cold.

Trouble is, cold resets take quite a bit longer than warm resets.

However, there are situations where a cold reset would be nice.
Specifically, after a stuck beacon, BB/MAC hang, stuck calibration results,
etc.

The vendor HAL has a separate method to set the reset reason (which is
how HAL_RESET_BBPANIC gets set) which informs the HAL during the reset path
why it occured.  This is almost but not quite the same; I may eventually
unify both approaches in the future.

This commit just extends HAL_RESET_TYPE to include both status (eg BBPANIC)
and type (eg do COLD.)  None of the HAL code uses it yet though;  that'll
come later.

It also is a big no-op in each HAL - I need to go teach each of the HALs
about cold/warm reset through this path.

72683266d0 Fix pagelist bus_dmamap_t map handling. Memory for pagelist is allocated
by bus_dmamem_alloc() which creates associated bus_dmamap_t map for us.
When this memory is freed by bus_dmamem_free(), the map is freed as well.

Thus there is no need to free it explicitly by bus_dmamap_destroy(),
which leads to double freeing.

dc809fc15f Flip on fast frames support for AR5416 and AR9300 series NICs.
This was off because the net80211 aggregation code was using the same
state pointers for both fast frames and ampdu tx support which led to some
pretty unfortunate panic-y behaviour.

Now that net80211 doesn't panic, let's flip this back on.

It doesn't (yet) do the horrific sounding thing of A-MPDU aggregates
of fast frames; that'll come next.  It's a pre-requisite to supporting
AMSDU + AMPDU anyway, which actually speeds things up quite considerably
(think packing lots of little ACK frames into a single AMSDU.)

Tested:

* QCA955x SoC, AP mode
* AR5416, STA mode
* AR9170, STA mode (with local fast frame patches)
