6256e57ba9 Implement CloudABI memory management system calls.
Add support for the <sys/mman.h> functions by wrapping around our own
implementations. There are no kern_*() variants of these system calls,
but we also don't need them in this case. It is sufficient to just call
into the sys_*() functions.

6e5fcd99df Add a sysentvec for CloudABI on x86-64.
Summary:
For CloudABI we need to put two things on the stack of new processes:
the argument data (a binary blob; not strings) and a startup data
structure. The startup data structure contains interesting things such
as a pointer to the ELF program header, the thread ID of the initial
thread, a stack smashing protection canary, and a pointer to the
argument data.

Fetching system call arguments and setting the return value is similar
to FreeBSD. The only differences are that system call 0 does not exist
and that we call into cloudabi_convert_errno() to convert the error
code. We also need this function in a couple of other places, so we'd
better reuse it here.

6d338f9a81 Import the CloudABI datatypes and create a system call table.
CloudABI is a pure capability-based runtime environment for UNIX. It
works similar to Capsicum, except that processes already run in
capabilities mode on startup. All functionality that conflicts with this
model has been omitted, making it a compact binary interface that can be
supported by other operating systems without too much effort.

CloudABI is 'secure by default'; the idea is that it should be safe to
run arbitrary third-party binaries without requiring any explicit
hardware virtualization (Bhyve) or namespace virtualization (Jails). The
rights of an application are purely determined by the set of file
descriptors that you grant it on startup.

The datatypes and constants used by CloudABI's C library (cloudlibc) are
defined in separate files called syscalldefs_mi.h (pointer size
independent) and syscalldefs_md.h (pointer size dependent). We import
these files in sys/contrib/cloudabi and wrap around them in
cloudabi*_syscalldefs.h.

We then add stubs for all of the system calls in sys/compat/cloudabi or
sys/compat/cloudabi64, depending on whether the system call depends on
the pointer size. We only have nine system calls that depend on the
pointer size. If we ever want to support 32-bit binaries, we can simply
add sys/compat/cloudabi32 and implement these nine system calls again.

The next step is to send in code reviews for the individual system call
implementations, but also add a sysentvec, to allow CloudABI executabled
to be started through execve().

more in the projects/ifnet. Moving out of contrib also allows to remove

9778bf377b Add initial support for the HAL channel survey support to the AR9300 HAL.
This is used by the 'athsurvey' command to print out channel survey
statistics - % busy times transmit, receive and airtime.

It's as buggy and incomplete as the rest of the HAL survey support -
notably, tying into the ANI code to read channel stats and occasionally
getting garbage counters isn't very nice.  It also doesn't (yet!) get
channel survey information during a scan.  But it's good enough for
basic air-time debugging, which is why I'm committing it in this state.

caa918bd3b Add ath_hal_setbeacontimers() to the AR9300 HAL.
This is a custom FreeBSD HAL method that is used by the TDMA code
to program the beacon timers directly without any guesswork/assumptions
by the HAL.

This brings up basic TDMA master/slave support on the AR9380 HAL,
however there are other issues preventing it from being stable.
(I'm seeing beacon interval instability, which may be due to
busy 2GHz air, but also may be due to some HAL configuration
issues with regards to ANI, or hardware timer programming, etc.)

* AR9331 (Carambola2), STA, AP, adhoc and TDMA master mode.

06f874e1f9 Remove the reserved pin 11 from the HAL check.
The QCA9565 can have RFKILL on GPIO Pin 11, and thus we need to configure
it up correctly or the NIC may not function.

I'm not sure why the AR9382 can't use GPIO 8 / GPIO 11 ; it's likely
hooked up to some external LNA or filter.  The real solution is to
make it only block pin 8 / pin 11 for AR9382, but the AR9382 probes
like an AR9380.  Sigh.

4c918926cd Add x2APIC support. Enable it by default if CPU is capable. The
hw.x2apic_enable tunable allows disabling it from the loader prompt.

To closely repeat effects of the uncached memory ops when accessing
registers in the xAPIC mode, the x2APIC writes to MSRs are preceeded
by mfence, except for the EOI notifications.  This is probably too
strict, only ICR writes to send IPI require serialization to ensure
that other CPUs see the previous actions when IPI is delivered.  This
may be changed later.

In vmm justreturn IPI handler, call doreti_iret instead of doing iretd
inline, to handle corner conditions.

Note that the patch only switches LAPICs into x2APIC mode. It does not
enables FreeBSD to support > 255 CPUs, which requires parsing x2APIC
MADT entries and doing interrupts remapping, but is the required step
on the way.

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.
