Having ncneg diverge with the actual length of the ncneg tailq causes
NULL dereference.
Add assertion that an entry taken from ncneg queue is indeed negative.

Pass MAP_STACK_GROWS_DOWN and MAP_STACK_GROWS_UP flags to
vm_map_insert() from vm_map_stack(), to really turn off coalescing
code and call to vm_map_simplify_entry() [1].

preadbuffer() maintained a flag whether there was any non-whitespace
character. This flag is only useful when history is enabled (in that case,
lines containing only whitespace are not added to history). Instead, check
using strspn() when history is enabled.
There is an approximate 2% speedup when running
sh -c '. /etc/rc.subr; . /etc/defaults/rc.conf; source_rc_confs'
with hot cache.
The handler is now called after the register value is updated in the virtual
APIC page. This will make it easier to handle APIC-write VM-exits with APIC
register virtualization turned on.
Additionally, mask all the LVT entries when the vlapic is software-disabled.
This seems to cause issues with jemalloc + {dhclient, sshd}.
Thus, revert this for now until the root cause can be found and
fixed.
This should quieten some runtime problems with the Raspberry Pi.

This fixes the problem, when gmirror starts again just after stop.
The problem occurs when gmirror's component has geom label with equal size.
E.g. gpt and gptid have the same size as partition, diskid has the same
size as entire disk. When gmirror's geom has been destroyed, glabel
creates its providers and this initiate retaste.
Now "gmirror destroy" command is available. It destroys geom and also
erases gmirror's metadata.

The handlers are now called after the register value is updated in the virtual
APIC page. This will make it easier to handle APIC-write VM-exits with APIC
register virtualization turned on.
Additionally, we need to ensure that the value of these registers is always
correctly reflected in the virtual APIC page, because there is no VM exit
when the guest reads these registers with APIC register virtualization.
INET6 socket when needed to allow pfctl to work on noinet and noinet6
kernels (and try to provide a fallback using AF_LINK as best effort).
Adjust the Makefile to also respect relevant src.conf(5) options
for compile time decisions on INET and INET6 support.

that we don't have a good way (yet) to iterate over the mapped pages by
virtual address and simply try each page within the range. Given that we
call pmap_remove() over the entire 2^63 bytes of address space, it takes
a while for pmap_remove to have tried all 2^50 pages.
By using pmap_remove_pages() we use the PV list to find all mappings.

X86: cvtpi2ps is just an SSE instruction with MMX operands. It has no AVX
equivalent.
Give it the right register format so we can also emit it when AVX is enabled.
This should fix a "Cannot select: intrinsic %llvm.x86.sse.cvtpi2ps" fatal error
in clang while building the gnuradio port for amd64.

- Host Identity Protocol (RFC5201)
- Shim6 Protocol (RFC5533)
- 2x experimentation and testing (RFC3692, RFC4727)
This does not indicate interest to implement/support these protocols,
but they are part of the "IPv6 Extension Header Types" [1] based on RFC7045
and might thus be needed by filtering and next header parsing
implementations.

X-Comment: I am not the new maintainer; chime in, it's ours.
When building the system from outside the chroot as part of the release
process, ensure the objdir is within the chroot so that the whole output
of the release.sh script is self-contained in a single directory.
Use CHROOTDIR/tmp/obj instead of CHROOTDIR/usr/obj to minimize possible
interferences with the output of the build itself.
