syslog(3), routines used in write_warmstart(), and exit(3) are all
signal-unsafe.  Instead, set a signal-safe flag and check the flag in the

9fbe631a1a [net80211] convert all of the WME use over to a temporary copy of WME info.
This removes the direct WME info access in the ieee80211com struct and instead
provides a method of fetching the data.  Right now it's a no-op but eventually
it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm,
upcoming ath10k work) as things like p2p support require this kind of behaviour.

Tested:

* ath(4), STA and AP mode

TODO:

* yes, this is slightly stack size-y, but it is an important first step
  to get drivers migrated over to a sensible WME API.  A lot of per-phy things
  need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.

cb1101afd7 shutdown: Assume absolute time is in the future
The original bug describes it best:

When an absolute time is specified to shutdown, the program's
behavior depends on whether that time has passed during the
current calendar day.  POLA would suggest that for shutdown,
whose time argument is always supposed to be in the future,
absolute times specified without a specific date should refer
to the next occurrence of that time, rather than erroring out
if that time has already passed during the current day.

It does not change anything in the behavior of trap_pfault(), while
eliminating obfuscation of jumping to the code which checks for the
condition reversed of the goto cause.  Also avoid force initialize the
rv variable, since it is now only accessed after storing vm_fault()

9997c0481c Do not let vm_daemon run unbounded.
On a load where single anonymous object consumes almost all memory on
the large system, swapout code executes the iteration over the
corresponding object page queue for long time, owning the map and
object locks.  This blocks pagedaemon which tries to lock the object,
and blocks other threads in the process in vm_fault() waiting for the
map lock.

Handle the issue by terminating the deactivation loop if we executed
too long and by yielding at the top level in vm_daemon.

7167e16b49 Remove sys/mips/rmi. It's been unmaintained since 2011. This hardware
is now unobtanium. It's only had API changes in the last 7 years, and
is responsible for a very large number of them. In addition, there's a
lot of code that reimplements base FreeBSD functionality, diminishing
the chances it still works. Without hardware to teset it on, or
prospects of obtaining such hardware and without vendor support, it's
time to move on.

ada611f6ad Retire old ADM 5120 port. It never grew much beyond the original port.
It came into the tree with the project/mips merge 8 years ago. At the
time, it was hard to find a board with enough RAM to run. Now FreeBSD
requires at least 2x the RAM it did then. No changes have happened to
this port apart from API churn and license tagging since then. It ran
OK at the time it was committed, but no sightings in the wild have
happened since shortly after it was committed.

https://www.linux-mips.org/wiki/Adm5120_devices lists a bunch of
boards that were available 5 years ago (but are no longer
available). The beefiest one had only 64MB of RAM which is too
small. The Mirktik RB1xx never had more than 32MB.

Also remove confusing QEMU config file that never ever worked in QEMU
for mips. MALTA is used for that. Another of my past mistakes, false
starts that never amounted to anything.

5daa7f27c5 Remove sys/mips/alchemy. It was still-born when I committed it and it
never got better. It never worked on real hardware and is still mostly
stubs after 8 years when I added it. It has had no real update in that
time apart from API churn. It was added just so it didn't get lost in
the project/mips merge, but maybe it should have been lost as nothing
has come of it. It is time to give up the ghost on this one.

b6f4732cb3 Add a validbcd() routine that uses the bcd2bin_data[] array and returns a
bool indicating whether the input value represents a valid BCD byte.

The existing bcd2bin() routine will KASSERT if asked to convert a bad value,
but sometimes the kernel has to handle BCD data from untrusted sources, so
this will provide a mechanism to validate data before attempting conversion.

This would be have easier/cleaner if the bcd2bin_data[] array contained an
out-of-range value (such as 0xff) in the infill locations that aren't valid,
but it's a global symbol that might be referenced by out-of-tree code
relying on the current scheme, so I'm leaving that alone.

The h3 will be added at a later time after some testing, due to a silicon
bug that causes the rootkey (at least) to be read incorrectly unless first
read via the control register.

0337438d5d Wrap includes in sys/tslog.h with #ifdef TSLOG.
This is necessary because some non-kernel code #defines _KERNEL and then
includes kernel headers; as a result, it was getting conflicting versions
of curthread and curproc.  Non-kernel code should probably refrain from
defining _KERNEL, but for now hiding these indirect inclusions fixes the
build.

e93e5bb0fa Allow use of .WAIT in the LOCAL_DIRS and LOCAL_LIB_DIRS lists.
A comment in Makefile.inc1 has long stated that LOCAL_DIRS are built last,
after the base system.  Incremental improvements in parallel building over
the years have led to LOCAL_DIRS being built in parallel with base system
directories.  This change allows the .WAIT directive to appear in LOCAL_DIRS
and LOCAL_LIB_DIRS lists to give the user some control over parallel
building of local additions.

8b8a7c43a9 Instrument "boot holds" for the benefit of the TSLOG framework. These
are places where the "main thread" of the booting kernel (either the
thread which later becomes swapper or the thread which later becomes
init) has to stop and wait for action to take place in another thread
before continuing.

There are currently three such holds:
1. The intr_config_hooks SYSINIT waits for hooks registered via the
config_intrhook_establish function; this allows (typically) devices
which need interrupts enabled to complete their initialization to do
so before root is mounted.

2. The g_waitidle function waits for the GEOM event queue to be empty;
this ensures that all of the disks which have been attached have been
tasted before we attempt to mount root.

3. The vfs_mountroot_wait function (in addition to calling g_waitidle)
waits for holds registered via root_mount_hold; among other things, this
is used by the USB subsystem to ensure that we don't fail to mount root
if it's located on a USB disk which takes a while to probe.
