It is nice to have, however, the location of this information means that
it will naturally be missed by developers adding or removing directories
to the layout, so it trends out-of-date and it is out-of-date.
The target audience for hier(7) is users and administrators. It is not
expected to be a place that programmers should go to learn about the
purposes of the different C headers provided by FreeBSD.
Program authors needing FreeBSD-specific interfaces or libraries
(#include <sys/queue.h>, for instance) will either be following a more
detailed man page, or consulting the header contents directly. Folks
targeting standardized headers (#include <sys/time.h>) will not need
hier(7) to tell them where those headers are under /usr/include.
In other words, this is more detail than necessary for this document.
I'd go as far as to say that many of the existing entries in this list
do little more than parrot the name of the directory.
With all this in mind, let's drop the maintenance burden.

Commit 281402e0a5 ("arm64: Shave off two instructions in exceptions")
removed the instruction that set the frame pointer (x29) as it appeared
to be unused.
The frame pointer is used in arm64/db_trace.c:db_stack_trace_cmd() when
unwinding state, and hence still needs to be set.
Add back the instruction to save_registers to properly update frame
pointer.

The pam ZTS tests were reporting a buffer overflow on F38, possibly
due to F38 now setting _FORTIFY_SOURCE=3 by default. gdb and
valgrind narrowed this down to a snprintf() buffer overflow in
zfs_key_config_modify_session_counter(). I'm not clear why this
particular snprintf() was being flagged as an overflow, but when
I replaced it with an asprintf(), the test passed reliably.

When performing an "upgrade" (moving between FreeBSD releases, as
opposed to "update" which merely applies security/errata updates
to the installed release) FreeBSD Update:
1. Generates a list of "files needing to be merged", namely those
files which don't match the version installed in the "old" release
and have paths matching the MergeChanges configuration directive
(by default, /boot/device.hints and everything under /etc/).
and later on,
2. Compares the currently-installed files to the versions in the
"new" release, removing index entries for files which "don't need
to be updated because they're not changing".
Unfortunately if a file falls into both of these categories -- that
is to say, if a file in /etc/ is the same as the version in the new
release and not the same as the version in the old release -- the
resulting "merge" step saw that the file was no longer listed as
being part of the new release, resulting in the file being deleted.
For the first 18 years of FreeBSD Update's existence, this never
happened, since $FreeBSD$ tags resulted in "new release" files
always being different from any files systems would already have
installed.
This commit fixes this behaviour by only placing a file into the
"files needing to be merged" list if it does not match the version
in the old release *or* the version in the new release.

When the ktls_buffer zone needs to expand, it may fail due
to a lack of physically contiguous memory. We tried to rectify
that by introducing an alloc thread to provide a context where
it is harmless to sleep, and letting that thread repopulate
the ktls_buffer zone.
However, it turns out that M_WAITOK is not enough, and we
must call vm_page_reclaim_contig_domain() to reclaim contig
memory. Worse, M_WAITOK results in the allocation essentially
busy-looping around vm_domain_alloc_fail() returning EAGIN,
causing vm_page_alloc_noobj_contig_domain() to loop and resulting
in the alloc thread consuming 100% CPU.
To fix this, we change the alloc thread to call
vm_page_reclaim_contig_domain_ext()
In order to prevent the busy loop around vm_domain_alloc_fail(), we
must change the uma_zalloc flags to M_NORECLAIM | M_NOWAIT. However,
once that is done, these allocations become no different than the
allocations done in the critical path in ktls_buffer_alloc(), so its
best to just eliminate them.
Since we're no longer doing allocations but just calling
vm_page_reclaim_contig_domain_ext(), the name has changed to the ktls
reclaim thread.

Implement vm_page_reclaim_contig_domain_ext() to reclaim multiple
contiguous regions at once. This makes it more efficient for users
that need multiple contiguous regions to reclaim those regions
efficiently.
This is needed because callers like ktls may need to reclaim many
contiguous regions, and each scan of physical memory can take
multiple seconds on a large memory machine (order of 100GB of
RMA). Rather than modifying the core algorithm, I extended
vm_page_reclaim_contig_domain() to take a "desired_runs" argument to
allow the caller to request that it reclaim more than just a single
run. There is no functional change intended for all existing
callers.
The first user for this interface is the ktls code
(https://reviews.freebsd.org/D39421). By reclaiming multiple runs,
ktls goes from consuming hours of CPU to refill its buffer zone to
just seconds or minutes.

With large numbers of CPUs, the calculation of the maximum lock delay
could overflow, leading to an unexpectedly low delay. In fact, the
maximum delay would calculate to 0 on systems with between 128 and
255 cores (inclusive). Also, when calculating the new delay in
lock_delay(), the delay would overflow if the old delay was >= 32,768.
This commit fixes these two overflows. It also updates the maximum
delay from 32,678 to SHRT_MAX.
