The '%I' format in the kern.corefile sysctl limits the number of
core files that a process can generate to the number stored in the
debug.ncores sysctl. The '%I' format is replaced by the single digit
index. Previously, if all indexes were taken the kernel would overwrite
only a core file with the highest index in a filename.
Currently the system will create a new core file if there is a free
index or if all slots are taken it will overwrite the oldest one.

Update carp to set DSCP value CS7(Network Traffic) in the flowlabel field of
packets by default. Currently carp only sets TOS_LOWDELAY in IPv4 which was
deprecated in 1998. This also implements sysctl that can revert carp back to
it's old behavior if desired.
This will allow implementation of QOS on modern network devices to make sure
carp packets aren't dropped during interface contention.

Several ioctls are unused in pf, in the sense that no base utility
references them. Additionally, a cursory review of pf-based ports
indicates they're not used elsewhere either. Some of them have been
unused since the original import. As far as I can tell, they're also
unused in OpenBSD. Finally, removing this code removes the need for
future pf work to take them into account.

The kernel code assumes that nfsdargs.addr == NULL and nfsdargs.addrlen == 0
when there is no "-p" argument used for starting the nfsd.
This small patch ensures this is the case. In practice, I believe this always
happened, since "nfsdargs" was the last element on the stack for "main()",
but this little patch ensures it will be the case.
Spotted by inspection while adding a new optional field for "-p".
Convert integer structure flags to use um_flags:
int um_candelete; /* devvp supports TRIM */
int um_writesuspended; /* suspension in progress */
become:
#define UM_CANDELETE 0x00000001 /* devvp supports TRIM */
#define UM_WRITESUSPENDED 0x00000002 /* suspension in progress */
This is in preparation for adding other flags to indicate forcible
unmount in progress after a disk failure and possibly forcible
downgrade to read-only.
No functional change intended.

Currently the mtree calls in Makefile.inc1 all change the directory owner
to match the spec file. However, we should not be doing this during
distributeworld if -DNO_ROOT is passed. Additionally, when creating the
WORLDTMP directory hierachy there is no need to change the owner to root so
we now always pass the -W flag when populating WORLDTMP.
This is also required for building FreeBSD on Linux/Mac since the required
groups/users will not exist there which is how I discovered this issue.

Summary: If the chosen console is not the OPAL uart, but OPAL uart devices
exist, the console device doesn't attach properly, and faults in the interrupt
handler, with a NULL pointer dereference. To fix this, and as a byproduct, also
support multiple OPAL consoles, refactor to have the console getc callback use
the appropriate softc instead of the global console_sc, which may be NULL in the
case of a different device being the console.

Previously newvers.sh passed --work-tree=${VCSDIR}/.. when invoking git.
When using git worktree .git is actually a file, not a directory, and
.git/.. is not a valid path. Although it appears git handles this
internally (perhaps it normalizes the path first), it is simple enough
for the script to store both the working tree top-level directory and
the VCS (.git) directory, so do so.

If a pNFS service was set up where the number of DSs equals the mirror level
and then a DS was disabled, the service would create files with duplicate
entries for the same DS. This bug occurred because I didn't realize that
TAILQ_FOREACH_FROM() would start at the beginning of the list when the
inital value of the variable was NULL.
This patch also changes the pNFS server DS file creation code so that it
creates entrie(s) with 0.0.0.0 IP address when it cannot create mirror level
files due to lack of DSs.
The patch only affects the pNFS service and only when it was created with
a number of DSs equal to the mirror level and mirroring is enabled.
Includes ntp_adjtime, auditctl, acct, auditon, and clock_settime. Includes
quotactl, mount, nmount, swapon, and swapoff in failure mode only. Success
tests for those syscalls will follow. Also includes reboot(2) in failure
mode only. That one can't be tested in success mode.

Doing so ensures that all threads sharing the pmap have a consistent
view of the mapping. This fixes the problem described in the commit
log messages for r329254 without the overhead of an extra fault in the
common case. Once other pmap_enter() implementations are similarly
modified, the workaround added in r329254 can be removed, reducing the
overhead of CoW faults.
With this change we can reuse the PV entry from the old mapping,
potentially avoiding a call to reclaim_pv_chunk(). Otherwise, there is
nothing preventing the old PV entry from being reclaimed. In rare
cases this could result in the PTE's page table page being freed,
leading to a use-after-free of the page when the updated PTE is written
following the allocation of the PV entry for the new mapping.

When 2GB of memory is enabled for QEMU's Malta emulation, the physical
memory ends at an address of 2^32 - 1. This causes an integer overflow
to zero when computing the upper bound of the second phys_avail[] range.
As a result, FreeBSD/mips kernels were only using the first 256MB of
RAM and ignoring the remaining 1.75GB. To work around this, truncate
the extended memory size to 2GB minus one page for 32-bit mips kernels.

SDHOST is another SD controller that is present on Raspberry Pi (the
other one is SDHC and handled by bcm2835_sdhci driver). Both
controllers are capable of providing interface to SD card, actual
configuration can be set in dtb file. At the moment custom DTBs for
RPi/RPi2 have sdhost node disabled. On RPi3 sdhost is disabled in
snapshot images by applying mmc.dtbo overlay. To enalbe both devices
user has to edit config.txt on FAT partition and remove or comment
"dtoverlay=mmc" line.
When no overlay applied on RPi3 SDHOST controls SD card and SDHC
interface can be used for SDIO. mmc.dtbo overlay disables SDHOST node
and switches SD card over to SDHC. Likewise sdhost.dtbo overlay (not
currently included in snapshot image, but can be obtained from firmare
repo[1]) disabled SDHC node and switch SD card over to SDHOST.
