Note that all of the current PCI-e registers are either 16 or 32-bits,

Certain invalid operations trigger hardware error conditions. Error
conditions that only halt one channel can be detected and recovered by
resetting the channel. Error conditions that halt the whole device are
generally not recoverable.
Add a sysctl to inject channel-fatal HW errors,
'dev.ioat.<N>.force_hw_error=1'.
When a halt due to a channel error is detected, ioat(4) blocks new
operations from being queued on the channel, completes any outstanding
operations with an error status, and resets the channel before allowing
new operations to be queued again.
Update ioat.4 to document error recovery; document blockfill introduced
in r290021 while we are here; document ioat_put_dmaengine() added in
r289907; document DMA_NO_WAIT added in r289982.

- I incorrectly claimed that unit change was 'i' -> 't'.
- The spec I reference in this commit is 2 decades newer than the one noted in
r289913. The fields in the SCSI mode database are more complete in the newer
spec, so it'll be easier for someone to decipher this commit if need be
later.

This is because the previous version was very obscure about the fact
that despite having Clang "on by default" for architectures such as powerpc, it
does not actually build due to the GCC it uses not having C++11 support.
Using an external compiler that supports C++11 does allow this to work.
This whole block should be rethought more given "on by default" is not
really default without extra work which could actually be surprising for
why Clang is showing up when using a newer GCC.

- Rather than allow 'make clean*' to ignore dependencies, make a static
list of targets in STANDALONE_SUBDIR_TARGETS that are known to be safe.
This allows a user to override them if needed and avoids adding this feature
to user-defined targets that are in ${SUBDIR_TARGETS}. [1]
- This now also allows to force SUBDIR_PARALLEL when calling these
targets, since no dependencies are needed.

properly recursed.
The .for loop was defining a ${__dir} variable that was being set at a
different evaluation time than the target itself, so every 'cd ${__dir}'
became the last value that was in ${__dir}. This resulted in 'make obj'
not properly being ran in the tree that would leave .depend files
scattered around when 'make all' was ran in rescue/.
To fix this, define a CRUNCH_SRCDIR_* for every prog if it does not
already have one and then use that variable in every relevant place.
This allows simplifying some logic as well.

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.

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.

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
