* Add a comment about the parameters I should support, stolen shamelessly
from iwn(4);
* Implement the rate bit for the raw transmit path;
* Print out the host-order versions of each of the transmit bits, so
I have a hope in heck of debugging why things are going wrong.
This still doesn't fix 5GHz in the office but that's likely due to a lot
of other configuration parameters being 2GHz-specific. That'll come next.
Tested:
* AR9170 + AR9103 (2/5GHz) 2x2, 5GHz association
Replace custom Linux-like logging with a thin shim around
device_printf(), when the softc is available.
In ioat_test, shim around printf(9) instead.

This should export all of the same information as the Linux ntb_hw_intel
debugfs info file, but with a bit more structure, in the sysctl tree
rooted at 'dev.ntb_hw.<N>.debug_info'.
Raw registers are marked as OPAQUE because reading them on some hardware
revisions may cause a hard lockup (NTB errata). They can be read with
'sysctl -x dev.ntb_hw.<N>.debug_info.registers'. On Xeon platforms,
some additional registers are available under 'registers.xeon_stats' and
'registers.xeon_hw_err'. They are exported as big-endian values so that
the 'sysctl -x' output is legible.
Shrink the feature mask to 32 bits so we can use the %b formatter in
'debug_info.features'.

This partially reverts r284685. An attempt was made in r285295 to fix this
but was not enough. There were still $${} vars in the code that should have
been using the ${_page} and ${_sect} vars, but the bigger problem was that
.for cannot be used on .ALLSRC as it is not defined when the .for is evaluated.
Using ${MAN} here in a .for loop doesn't work either as the paths are not
expanded right for lib/libc/ subdirs despite having a .PATH set for all
of them.
Add some comments around long .else and .endif as well.

linux_syscallnames[] from linux_* to linux32_* to avoid conflicts with
linux64.ko. While here, add support for linux64 binaries to systrace.
- Update NOPROTO entries in amd64/linux/syscalls.master to match the
main table to fix systrace build.
- Add a special case for union l_semun arguments to the systrace
generation.
- The systrace_linux32 module now only builds the systrace_linux32.ko.
module on amd64.
- Add a new systrace_linux module that builds on both i386 and amd64.
For i386 it builds the existing systrace_linux.ko. For amd64 it
builds a systrace_linux.ko for 64-bit binaries.

linux: fix handling of out-of-bounds syscall attempts
Due to an off by one the code would read an entry past the table, as
opposed to the last entry which contains the nosys handler.
Don't run the selftest until after we've enabled bus mastering, or the
DMA engine can't copy anything for our test.
Create the ioat_test device on attach, if so tuned. Destroy the
ioat_test device on teardown.
Replace deprecated 'CALLOUT_MPSAFE' with correct '1' in callout_init().

Similar to r286787 for x86, this treats userspace buffers the same as unmapped buffers and no longer borrows the UVA for sync operations.

It turns out that it is pretty easy to make CloudABI work on ARM64. We
essentially only need to copy over the sysvec from AMD64 and ensure that
we use ARM64 specific registers.
As there is an overlap between function argument and return registers,
we do need to extend cloudabi64_schedtail() to only set its values if
we're actually forking. Not when we're creating a new thread.

For CloudABI we need to initialize the registers of new threads
differently based on whether the thread got created through a fork or
through simple thread creation.
Add a flag, TDP_FORKING, that is set by do_fork() and cleared by
fork_exit(). This can be tested against in schedtail.

In order to make it easier to support CloudABI on ARM64, move out all of
the bits from the AMD64 cloudabi_sysvec.c into a new file
cloudabi_module.c that would otherwise remain identical. This reduces
the AMD64 specific code to just ~160 lines.

This is an AR9331 part based on the AP121 reference design but with
32MB RAM. Yes, it has 4MB flash and it has no USB, so clever hacks
are required to get it up and working.
But boot/work it does.
This part seems to work bug-free with single byte TX/RX buffer alignment.
This drops the CPU requirement to bridge 100mbit iperf from 100% CPU
to ~ 50% CPU.
Tested:
* AP121 (AR9330) SoC, highly magic netbooted kernel + USB rootfs
due to 4mb flash, 16mb RAM; doing bridging between arge0 and arge1.
Notes:
* Yes, I likely can also turn this on for the AR934x SoC family now.
But since hardware design apparently follows similar branching
strategies to software design, I'll go and make sure all the AR934x's
that made it out into shipping products work before I flip it on.
these testcases don't need to be nested as much as bin/ls/ls_tests.sh
do when verifying ls -a, ls -A, etc. This allows the tests to make
all paths relative to the top of the temporary directory instead of
always tacking on $ATF_TMPDIR, thus complicating things unnecessarily
Create non-empty files in create_test_inputs as well now, similar to
create_test_inputs2 in bin/ls/ls_tests.sh
Compare the input files to the output file contents using diff where
possible:
- Skip over the fifo comparison for now because it always fails
- Skip over the symlink comparison on cd9660 because it always fails
today
