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.

- 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

The test logic now preallocates memory before running the test.
The buffer size is now configurable. Post-copy verification is
configurable. The number of copies to chain into one transaction (one
interrupt) is configurable.
A 'duration' mode is added, which repeats the test until the duration
has elapsed, reporting the B/s and transactions completed.
ioatcontrol.8 has been updated to document the new arguments.
Initial limits (on this particular Broadwell-DE) (and when the
interrupts are working) seem to be: 256 interrupts/sec or ~6 GB/s,
whichever limit is more restrictive.
Unfortunately, it seems the interrupt-reset handling on Broadwell isn't
working as intended. That will be fixed in a later commit.

The FDT bindings for eeprom parts don't include any metadata about the
device other than the part name encoded in the compatible property.
Instead, a driver is required to have a compiled-in table of information
about the various parts (page size, device capacity, addressing scheme). So
much for FDT being an abstract description of hardware characteristics, huh?
In addition to the FDT-specific changes, this also switches to using the
newer iicbus_transfer_excl() mechanism which holds bus ownership for the
duration of the transfer. Previously this code held the bus across all
the transfers needed to complete the user's IO request, which could be
up to 128KB of data which might occupy the bus for 10-20 seconds. Now the
bus will be released and re-aquired between every page-sized (8-256 byte)
transfer, making this driver a much nicer citizen on the i2c bus.
The hint-based configuration mechanism is still in place for non-FDT systems.
Michal Meloun contributed some of the code for these changes.
while holding exclusive ownership of the bus. This is the routine most
slave drivers should use unless they have a need to acquire and hold the
bus across a series of related operations that involves multiple transfers.
Now it can be used to effectively "build in a subdir". It will use the
'cross-tools', 'libraries', and 'includes' phases of 'buildworld' to properly
setup a WORLDTMP to use. Then it will build 'everything' only in the
listed SUBDIR_OVERRIDE directories. It is still required to list custom
library directories in LOCAL_LIB_DIRS if SUBDIR_OVERRIDE is something
that contains libraries outside of the normal area (such as
SUBDIR_OVERRIDE=contrib/ofed needing LOCAL_LIB_DIRS=contrib/ofed/usr.lib)
Without these changes, SUBDIR_OVERRIDE with buildworld was broken or hit
obscure failures due to missing libraries, includes, or cross compiler.
SUBDIR_OVERRIDE with 'make <target that is not buildworld>' will continue to
work as it did before although its usefulness is questionable.
With a fully populated WORLDTMP, building with a SUBDIR_OVERRIDE with
-DNO_CLEAN only takes a few minutes to start building the target
directories. This is still much better than building unneeded things via
'everything' when testing small subset changes. A BUILDFAST or
SKIPWORLDTMP might make sense for this as well.
- Add in '_worldtmp' as we still need to create WORLDTMP as later targets,
such as '_libraries' and '_includes' use it. This probably was avoiding
calling '_worldtmp' to not remove WORLDTMP for debugging purposes, but
-DNO_CLEAN can be used for that.
- '_legacy' must be included since '_build-tools' uses -legacy.
The SUBDIR_OVERRIDE change came in r95509, while -legacy being part
of build-tools came in r113136.
- 'bootstrap-tools' is still skipped as this feature is not for
upgrades.
- Fix buildworld combined with SUBDIR_OVERRIDE not installing all includes.
The original change for SUBDIR_OVERRIDE in r95509 kept '_includes'
and '_libraries' as building everything possible as the SUBDIR_OVERRIDE
could need anything from them. However in r96462 the real 'includes'
target was changed from manual sub-makes to just recursing 'includes'
on SUBDIR, thus not all includes have been installed into WORLDTMP since then
when combined with 'buildworld'.
This is not done unless calling 'make buildworld' as it would be
unexpected to have it go into all directories when doing 'make
SUBDIR_OVERRIDE=mydir includes'.
- Also need to build the cross-compiler so it is used with --sysroot.
If this is burdensome then telling the build to use the local compiler
as an external compiler (thus using a proper --sysroot to WORLDTMP) is
possible by setting CC=/usr/bin/cc, CXX=/usr/bin/c++, etc.
- Don't build the lib32 distribution with SUBDIR_OVERRIDE in buildworld
since it won't contain anything related to SUBDIR_OVERRIDE. Testing
of the lib32 build can be done with 'make build32'.
- Document these changes in build.7
