When inserting a partitioned disk, devfs and geom will announce the whole
disk before they announce the partition. If the partition containing ZFS
extends to one of the disk's extents, then zfsd will see a ZFS label on the
whole disk and attempt to online it. ZFS is smart enough to activate the
partition instead of the whole disk, but only if GEOM has already created
the partition's provider.

Not enabling FSGSBASE in %cr4 does not prevent reporting of the
feature by the CPUID instruction (blame Int*l). As result, kernels
which were run under monitors pretended that usermode cannot modify
TLS base without the syscall, while libc noted right combination of
capable CPU and the new kernel version, trying to use the WRFSBASE
instruction.
Really old hypervisors that cannot handle enablement of these features
in %cr4 would require the manual configuration, by setting the loader
tunable hw.cpu_stdext_disable=0x81

fgrep/grep -F will error out at runtime if compiled with a regex(3)
that does not define REG_NOSPEC or REG_LITERAL. glibc is one such regex(3)
implementation, and as it turns out they don't support literal matching at
all.
Provide a primitive literal matcher for use with glibc and other
implementations that don't support literal matching so that we don't
completely lose fgrep/grep -F if compiled against libgnuregex on stable/10,
stable/11, or other systems that we don't necessarily support.
This is a wholly unoptimized implementation with no plans to optimize it as
of now. This is due to both its use-case being primarily on unsupported
systems in the near-distant future and that it's reinventing the wheel that
we already have available as a feature of regex(3).

PCI express network cards.
There is currently no user-space support and this driver only supports
kernel side non-routable RoCE V1. The krping kernel module can be used
to test this driver. Full user-space support including RoCE V2 will be
added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise
this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel
module will only be built when WITH_OFED=YES is specified.

newvers.sh looks for a .vcs subdirectory (e.g. .git, .svn) to determine
which vcs info tool to run (e.g., git rev-parse, svn info).
(As of r308789 if a .vcs subdirectory is not found at ${TOPDIR} then
newvers.sh walks up successive parent directories, testing for the .vcs
subdirectory at each step. This is done in case the FreeBSD source is
built in a subdirectory as part of some larger project, but either way
newvers.sh still tests for the .vcs subdirectory.)
However, when using git worktree there is no .git subdirectory but
rather a plain text .git file which contains a reference to the main
working tree.
Change findvcs() to test that the .vcs entry exists, regardless of type.

Rather than repeatedly nesting loops, separate concerns with a single loop
per call stack level. Use a table to drive the recursive routine. Handle
missing topology layers more gracefully (infer a single unit).
Analyze some additional optional layers which may be present on e.g. AMD Zen
systems (groups, aka dies, per package; and cachegroups, aka CCXes, per
group).
Display that additional information in the boot-time topology information,
when it is relevent (non-one).

The aggregation created by llquantize() partitions values into buckets; the
lower bound of the bucket containing the largest values is b^{m+1}, where
b and m are the second and fourth parameters to the action, respectively.
Bucket bounds are stored in a 64-bit integer, and so the llquantize()
validation checks need to verify that b^{m+1} fits in 64 bits. However, it
was only verifying that b^{m-1} fits in 64 bits, so certain parameter
combinations could trigger assertion failures in libdtrace.

The full system memory barrier around a TLB invalidation is stricter than
required. It needs to wait on accesses to main memory, with just the weaker
store variant before the invalidate. As such use the dsb istst, tlbi, dlb
ish sequence already used in pmap.
The tlbi instruction in this sequence is also unnecessarily using a
broadcast invalidate when it just needs to invalidate the local CPUs TLB.
Switch to a non-broadcast variant of this instruction.
