Before r291643, adding new interface prefix had the following logic:
try_add:
EEXIST && (PINNED) {
try_del(w/o PINNED flag)
if (OK)
try_add(PINNED)
}
In r291643, deletion was performed w/ PINNED flag held which leaded
to new interface prefixes (like ::1) overriding older ones.
Fix this by requesting deletion w/o RTF_PINNED.

Strictly speaking, missing devinfo is error which can be caused
by instantiating child using device_add_child() instead of
BUS_ADD_CHILD(). However, we can tolerate it.

By using this functions, we can parse a list of tuples, each of them holds
xref and variable number of values.

LLE structure is mostly unchanged during its lifecycle: there are only 2
things relevant for fast path lookup code:
1) link-level address change. Since r286722, these updates are performed
under AFDATA WLOCK.
2) Some sort of feedback indicating that this particular entry is used so
we send NS to perform reachability verification instead of expiring entry.
The only signal that is needed from fast path is something like binary
yes/no.
The latter is solved by the following changes:
Special r_skip_req (introduced in D3688) value is used for fast path feedback.
It is read lockless by fast path, but updated under req_mutex mutex. If this
field is non-zero, then fast path will acquire lock and set it back to 0.
After transitioning to STALE state, callout timer is armed to run each
V_nd6_delay seconds to make sure that if packet was transmitted at the start
of given interval, we would be able to switch to PROBE state in V_nd6_delay
seconds as user expects.
(in STALE state) timer is rescheduled until original V_nd6_gctimer expires
keeping lle in STALE state (remaining timer value stored in lle_remtime).
(in STALE state) timer is rescheduled if packet was transmitted less that
V_nd6_delay seconds ago to make sure we transition to PROBE state exactly
after V_n6_delay seconds.
As a result, all packets towards lle in REACHABLE/STALE/PROBE states are handled
by fast path without acquiring lle read lock.

requests which page alignment + size is greater than MAXPHYS. Right
now md(4) over vnode would use the physical buffer of the size MAXPHYS
to map a data of size MAXPHYS + page offset of the user buffer. This
typically corrupts next pbuf, or, if the pbuf used was the last pbuf
in the map, the next page after the pbuf's map.
Split request up to the size of io which fits into pbuf KVA with
alignment, and retry if a part of the bio is left unprocessed.

These use ld(1), effectively -nostdlib, and don't need any of these
normal dependencies.
kmod builds also define PROG so just checking for KMOD here seems to be
the easiest to handle it.

RISC-V is a new ISA designed to support computer research and education, and
is now become a standard open architecture for industry implementations.
This is a minimal set of changes required to run 'make kernel-toolchain'

Rework stat2ascii preparing a buffer of what could be printed. This prevent the
risk of overflowing a static buffer.
Do not print those informations anymore in the "status" but into a new
"extra status" only printed if there are actually extra things to print.
Now add those extra informations:
* Thermal sensor temperature
* Cooling devices speed
* Voltage sensors, current consumption

A panicking thread always executes with a critical section held, so any
attempt to allocate or free memory while dumping will otherwise cause a
second panic. This can occur, for example, if xpt_polled_action() completes
non-dump I/O that was pending at the time of the panic. The fact that this
can occur is itself a bug, but asserting in this case does little but
reduce the reliability of kernel dumps.

http://www.t-es-t.hu/download/mips/md00090c.pdf this is bit 3 of the
config0 word, not bit 2. This should fix virtually indexed caches
(relatively new in the MIPS world, so no current platforms used this
and current code just uses it as an optimization). It was causing
false positives on newer platforms that default to large values for
the kseg0 cache coherency attribute.
