Hardware based profiling (e.g. hwpmc) is much better and produces more
useful results. Today the profiling lib archives (_p.a) serve no real
purpose other than increasing the library build time.
Both upstream and base system (in commit b762974cf4b9) Clang have been
modified to remove the special case for linking against these libraries.
Clang's -pg support and mcount() remain, so building with -pg can still
be used on code that the user builds; we just no longer provide prebuilt
libraries compiled with -pg.
Discussed on freebsd-hackers[1] / freebsd-current [2] in 2020 and
freebsd-arch [3] in 2021. A deprecation notice was added in
commit 175841285e28.

Otherwise bsd.dirs.mk will create the directory with the default
package (utilities) and we end up with a bunch of empty dirs managed
by this package while it shouldn't be the case.
The appropriate directory and name were assigned to the FILESDIR
grouping, but not the ALWAYS grouping where C.UTF-8 is actually
assigned. Add the appropriate bits for ALWAYSDIR, and remove an
obsolete *PACKAGE= assignment since C.UTF-8 is explicitly not included
in FILES.
Prior to this change, C.UTF-8 was being installed as
/usr/share/C.UTF-8.LC_CTYPE.

fspacectl(2) is a system call to provide space management support to
userspace applications. VOP_DEALLOCATE(9) is a VOP call to perform the
deallocation. vn_deallocate(9) is a public KPI for kmods' use.
The purpose of proposing a new system call, a KPI and a VOP call is to
allow bhyve or other hypervisor monitors to emulate the behavior of SCSI
UNMAP/NVMe DEALLOCATE on a plain file.
fspacectl(2) comprises of cmd and flags parameters to specify the
space management operation to be performed. Currently cmd has to be
SPACECTL_DEALLOC, and flags has to be 0.
fo_fspacectl is added to fileops.
VOP_DEALLOCATE(9) is added as a new VOP call. A trivial implementation
of VOP_DEALLOCATE(9) is provided.

g_alloc_event will allocate storage for an opaque event. g_post_event_ep
can use memory returned by g_alloc_event to send an event from a context
that might not be able to allocate the event. Occasionally, we can
alloate memory when we create an object, but not while we're destroy
it. This allows one to allocate at creation time memory to use when
destorying the object.

The syscall number is stored in the same register as the syscall return
on amd64 (and possibly other architectures) and so it is impossible to
recover in the signal handler after the call has returned. This small
tweak delivers it in the `si_value` field of the signal, which is
sufficient to catch capability violations and emulate them with a call
to a more-privileged process in the signal handler.
