This reverts commit bd72252aac.
The commit at hand breaks the build for all mips targets and does not
have a one-liner fix.
make[5]: "/usr/src/share/mk/sys.mk" line 169: Malformed conditional (${MACHINE_CPUARCH} == "mips" && ${COMPILER_TYPE} == "gcc")
Handle the case of a tagged command arriving when there's an untagged
one still outstanding gracefully instead of panicing.
While at it:
- Replace fancy arithmetics with a simple assignment as busy_itl can
only ever be either 0 or 1.
- Fix a comment typo in sym_free_ccb().
- In ___dma_getp(), remove dead code. [1]
- In sym_sir_bad_scsi_status(), add missing FALLTHROUGH. [2]
While at it:
- For getbaddrcb(), remove __unused from the nseg argument as it's in
fact used when compiling with INVARIANTS.
- In sym_int_sir(), ensure in all branches that cp is not NULL before
using it.

The following situation can trigger the deadlock:
1) Long time ago a_service was started through rc.d
2) We want to restart a_service and issue service a_service restart
3) rc.subr reads current process PID (via file or process),
sends TERM signal and runs pwait with PID harvested
4) a_service process dies very quickly so it's PID becomes available.
It is possible that while original process was running,
PID counter overflowed and pwait got assigned a_service's PID.
This patch ignores pid(s) to wait that are equal to pwait PID.

Some tests verify that the capgrp capability does not permit calls to
setgrent(3), but all tests need to ensure that they reset the
capability's group database handle, otherwise the local process and
casper process will be out of sync.
The cap_pwd tests already handle this.

Because the "files" and "compat" implementations failed to set the

the purpose of setgroupent(3). setpassent(3)'s implementation does not

The getpwent(3) and getgrent(3) implementations maintain some internal
iterator state. Interleaved calls to functions which do passwd/group
lookups using a key, such as getpwnam(3), would in some cases clobber
this state, causing a subsequent getpwent() or getgrent() call to
restart iteration from the beginning of the database or to terminate
early. This is particularly troublesome in programming environments
where execution of green threads is interleaved within a single OS
thread.
Take care to restore any iterator state following a keyed lookup. The
"files" provider for the passwd database was already handling this
correctly, but "compat" was not, and both providers had this problem
when accessing the group database.

PNP info definitions currently have an unfortunate requirement in that
they must follow the associated module definition in the module metadata
linker set. Otherwise devmatch can segfault while processing the linker
hints file since kldxref maintains the order in the linker set.
A number of drivers violate this requirement. In some cases this can
cause devmatch(8) to segfault when processing the linker hints file.
Work around the problem for now simply by adjusting the drivers.

I believe that rtld does not need to implement them, they are mostly for

For hardware offload solicited data may potentially be handled more
efficiently than unsolicited due to direct data placement. Or there
can be some unsolicited write buffering limitations. It may create
situations where FirstBurstLength limit is really useful.
Software driver though has no those factors, having to do memcopy()
any way and having no so hard limit on the temporary storage. Same
time more active use of unsolicited transfers allows to avoid some
of Ready To Transfer (R2T) PDU round-trip times and processing.
This change effectively doubles from 64KB to 128KB the maximum size
of write command that can be transferred within one link RTT. Tests
of (64KB, 128KB] QD1 writes mixed with simultaneous QD8 reads over
the same connection, increasing RTT, shows almost double write speed
and half latency, while we should be able to afford few megabytes of
RAM for additional buffering on a target these days.

If ${REPODIR}/${PKG_ABI} does not exist when we begin real-update-packages,
skip the comparison with the non-existent previous repository and just
finish the repo off. This allows external scripts to just assume they can
run `update-packages` rather than figuring out if they'd previously run
`packages` for this Version/Arch combo.
PKG_VERSION_FROM_DIR was added so that we could perhaps detect the three
distinct cases:
1.) If the repo has not yet been created, PKG_VERSION_FROM_DIR will be
empty.
2.) If the repo is in some intermediate state between created and fully
initialized, PKG_VERSION_FROM_DIR may point to the ABI directory.
3.) If the repo is fully initialized, then PKG_VERSION_FROM_DIR points to
the latest build to compare to.
Option #2 is explicitly unhandled at the moment, but this is no different
than it was before.

Since we use --input-type binary these options are rather meaningless. Both
binutils and elftoolchain ignore the option in this case, but LLVM does not,
and instead strips all symbols from the output file, causing missing symbols at
run time if building with llvm-objcopy. Thus simply remove the options; the
linux module has never included them for building its VDSO (added in r283407),
but for some reason the original commit of linux64 (r283424) added them.
These should however eventually be changed to use template assembly files as is
now done for firmware and MFS_IMAGE.

Currently only amd64, i386 and powerpc build VirtIO modules, yet all other
architectures have at least one kernel configuration that includes the
transport drivers, and so they lack drivers for all the devices they don't
statically compile into the kernel. Instead, enable the build everywhere so all
architectures have the full set of device drivers available.

Rather than have every device register itself for both virtio_pci and
virtio_mmio, provide a VIRTIO_DRIVER_MODULE wrapper to declare both,
merge VIRTIO_SIMPLE_PNPTABLE with VIRTIO_SIMPLE_PNPINFO and make the
latter register for both buses. This also has the benefit of abstracting
away the available transports and their names.

We must check MagicValue not just Version before anything else, and then
we must check DeviceID and immediately abort if zero (and this must not
be an error).
Do all this when probing rather than at the start of attaching as that's
where this belongs, and provides a clear boundary between the device
detection and device initialisation parts of the specified driver
initialisation process. This also means we don't create empty device
instances for placeholder devices, reducing clutter on systems that
pre-allocate a large number, such as QEMU's AArch64 virt machine (which
provides 32).

Use refcount(9) for both pr_ref and pr_uref in struct prison. This
allows prisons to held and freed without requiring the prison mutex.
An exception to this is that dropping the last reference will still
lock the prison, to keep the guarantee that a locked prison remains
valid and alive (provided it was at the time it was locked).
Among other things, this honors the promise made in a comment in
