Add cpuctl(4) ioctl CPUCTL_EVAL_CPU_FEATURES which forces re-read of
cpu_features, cpu_features2, cpu_stdext_features, and
std_stdext_features2.
The intent is to allow the kernel to see the changes in the CPU
features after micocode update. Of course, the update is not atomic
across variables and not synchronized with readers. See the man page

foundation for invoking efibootmgr as part of new-style EFI booting on
x86. On PS3 and PowerNV, which are booted using Linux kexec from petitboot
rather than by loader(8), install the kernel and the rest of /boot to a
FAT partition and set up the appropriate petitboot configuration file
there.
The new bootconfig installer stage can do platform-dependent modifications
more complex than partition layout and installation of boot blocks and can
be used to (as here) set up some special configuration files, run efibootmgr,
or boot0cfg.

o Use open + fstat rather than stat + open to avoid any races for a

o Use strlcpy instead of strcpy as a failsafe to knowing that the
strings can't possibly be larger than the buffer due to data
source limits (though in the future these limits might be more
dynamic).
o If we can't find the hints file, return rather than dereference

comes before a module entry. That's not allowed, but within the

devmatch(8) matchs up devices in the system device tree with drivers
that may match them. For each unattached device in the system, it
tries to find matching PNP info in the linker hints and prints modules
to load to claim the devices.
In --unbound mode, devmatch can look for drivers that have attached to
devices in the device tree and have plug and play information, but for
which no PNP info exists. This helps find drivers that haven't been
converted yet that are in use on this system.
In addition, the ability to dump out linker.hints is provided.
Future commits will add hooks to devd.conf and rc.d to fully automate
using this information.

After consultation with SPDX experts and their matching guidelines[1],
the licensing doesn't exactly match the BSD-2-Clause. It yet remains to be

When building the command to execute for compression, newsyslog was modifying
the generic arguments array instead of its own copy.
Meaning on the second file to compress with the same arguments, the command line

Fix it by creating one copy of the arguments per execution and modifying that
copy.

We may need to initialize multiple inode blocks before writing a given

certain inode allocation patterns could lead to a situation where it
wrote an inode to an uninitialized block. That inode might be clobbered
by a later initialization, resulting in a filesystem image containing
directory entries that point to a seemingly unused inode.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known

that the tags are considered only advisory and do not, in any way,
