defparam all of the config variables associated with SYSV IPC stuff.
The variables were removed from sys/conf/param.c and moved into the
SYSV IPC code, but config options were never propagated via any opt_*
file.

This should fix an issue reported on netbsd-users list from Dima Veselov.

Note that this does not address other parameters included in that report,
including CHILD_MAX and NOFILE; this commit only affects items related to
the SYSV IPC code.  Also note that this does not affect non-built-in
sysv_ipc modules, for which you need to update the Makefile to use any
non-standard config values - just like any other non-built-in modules
which have config params.

SIGTRAP. sigswitch() must acquite it internally anyway so this does not

Provide a code argument in kasan_mark(), and give a code to each caller.
Five codes used: GenericRedZone, MallocRedZone, KmemRedZone, PoolRedZone,

This can greatly help debugging complex memory corruptions.

(maxv)

Fix tiny race in pool+KASAN, that resulted in occasional false positives.

We were uselessly marking already valid areas as valid. When doing that,
our KASAN code emits two calls to kasan_markmem, and there is a very small
window where the area becomes invalid. So, if the area happens to be
already globally referenced, and if another thread happens to read the
buffer via this reference, we get a false positive.

This happens only with pool_caches that have a pc_ctor that creates a
global reference to the buffer, and there is one single pool_cache that
does that: 'file_cache'.

So now, two changes:

- In pool_cache_get_slow(), the pool_get() has already redzoned the
  object, so no need to call pool_redzone_fill().

- In pool_cache_destruct_object1(), don't re-mark the object. If there is
  no ctor pool_put is fine with already-invalid objects, if there is a
  ctor the object was not marked as invalid in the first place; so in
  either case, the re-marking is not needed.

Fixes PR/53674. Although very rare and difficult to reproduce, a local
quarantine patch of mine made the false positives recurrent.

a traditional value and accessing p_lflag to check for PL_PPWAIT shall

Overhaul the API used to fetch and store individual memory cells in
userspace.  The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms.  The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Implement a DIRTY flag (copied from sd(4)) so avoid flushing the cache if

command triggered by atactl sleep, when the device is open only by the atactl
command itself.
If a drive has no partition open and goes to sleep, the WDF_LOADED
flag is clear, and the next open will issue  wd_get_params() command.
But to wake up the drive a reset is required, and wd_get_params() doens't
issue a reset on timeout, so there's no way to wake up the disk.
Add a retry after reset to wd_get_params().

    zic now has an -r option to limit the time range of output data.
    For example, 'zic -r @1000000000' limits the output data to
    timestamps starting 1000000000 seconds after the Epoch.
    This helps shrink output size and can be useful for applications
    not needing the full timestamp history, such as TZDIST truncation;
    see Internet RFC 8536 section 5.1.  (Inspired by a feature request
    from Christopher Wong, helped along by bug reports from Wong and
    from Tim Parenti.)
