ccr depends on symbols exported by the cxgbe driver as well as having
a runtime dependency. While the runtime depenency was noted in the
manpage already, the compile-time dependency wasn't as clear.

If service code faulted, we might end up unwinding with interrupts
disabled. Top-level kernel code should have interrupts enabled, which
is enforced by checks.
Save %rflags before entering EFI, and restore to the known good value
on return. This handles situation with disabled interrupts on fault
and perhaps other potential bugs, e.g. invalid value for PSL_D.

the followup stopgap change, because I don't think it's a correct. I still

This change enables natural scrolling with two finger scroll enabled
and when user is using a trackpad (mouse and trackpoint are not affected).
Depending on trackpad model it can be activated with setting of
hw.psm.synaptics.natural_scroll or hw.psm.elantech.natural_scroll sysctl
values to 1.
Evdev protocol is not affected by this change too. Tune userland client
e.g. libinput to enable natural scrolling in that case.

In this case, a change was made in one-true-awk from *FS to
getsval(fsloc) in a line just after one of the lines that had the 0 ->
NULL change. It works both ways as far as I can tell. It looks like a
bug fix, but I've not tried to track down which ancient version of
one-true-awk it was in (github starts too late for tracking this
down). Before and after the changes the regression suite is passes
100% relative to the un-modified one-true-awk.
The conversion of 0 -> NULL required a rebase at some point, as noted
in r301289 when pfg commited it. In that rebase, three lines remained
that had been removed in a prior version of awk, and one of them had a
0 -> NULL change causing a conflict. The conflict should have been
resolved by removing the three lines, but wasn't. This introduces a
regression into f.split3 test which prior to this commit we were
failing, but a pure onetrueawk wasn't. Remove the offending 3 lines.
as part of a false start toward fine-grained reservation locking. In the
end, they were not needed, so eliminate them.
Order the parameters to vm_reserv_alloc_{contig,page}() consistently with
the vm_page functions that call them.
Update the comments about the locking requirements for
vm_reserv_alloc_{contig,page}(). They no longer require a free page
queues lock.
Wrap several lines that became too long after the "req" and "domain"
parameters were added to vm_reserv_alloc_{contig,page}().

Revert r301689 - one-true-awk: Avoid a NULL dereference.
I got this wrong and the coverity report doesn't match the NetBSD change,
which was thought for a different version.
The change wouldn't hurt but let's wait until upstream figures this out.
Other frameworks, such as googletest, should be added there as well,
once they become viable. For now let's keep it simple.

Note: this backs out a number of changes we've made to awk because
they aren't upstream, but are on the vendor branch. Those will be
reapplied. svn makes it needlessly difficult to know which ones, but
at least r315426, r301289, and maybe r301691, though there may be
others too. None of these are critical, so bisecting through this
point is safe for all but awk regression tests :).
As depicted in the comment: jid 0 always exists, but the lookup will fail as
it does not appear in the kernel's alljails list being a special jail. Some
callers will expect/rely on this, and we have no reason to lie because it
does always exist.

Upstream one-true-awk woke-up! Time to catch up. This may also revert
FreeBSD changes that we'd placed in the vendor branch in anticipation
of their inclusion in upstream. That's not yet the case, and these
will be resolved in the merge.
See FIXES for a complete list of bugs fixed (starting with the Jun 7,
2018 entry).
ASAN reports become a lot more useful with llvm-symbolizer in $PATH, and the
build is not much more time-consuming. The added benefit is that the
resulting reports will actually include symbol information; without, thread
trace information includes a bunch of addresses that immediately resolve to
an inline function in
^/contrib/compiler-rt/lib/sanitizer_common/sanitizer_common.h and take a
little more effort to examine.

This 'r' case should have belonged to the switch in the first place, but
I had somehow missed the switch when initially adding the rgrep link. The
zgrep script later came along and faithfully left this case standing alone,
so we will now go ahead and join it.
Nearby comment also adjusted a tad bit for wording and style.

another one in udp_output(). This one is a race condition.
We do check on the laddr and lport without holding a lock in
order to determine whether we want a read or a write lock
(this is in the "sendto/sendmsg" cases where addr (sin) is given).
Instrumenting the kernel showed that after taking the lock, we
had bound to a local port from a parallel thread on the same socket.
If we find that case, unlock, and retry again. Taking the write
lock would not be a problem in first place (apart from killing some
parallelism). However the retry is needed as later on based on
similar condition checks we do acquire the pcbinfo lock and if the
conditions have changed, we might find ourselves with a lock
inconsistency, hence at the end of the function when trying to
unlock, hitting the KASSERT.
