The older symbol hiding method breaks for MIPS. This implements
symbol hiding through renaming to a symbol name which is highly
unlikely to clash.
The NetBSD code didn't use byte-swapping macros for endian-awareness;
so it didn't work when cross-compiling a MIPS world on i386/amd64.
This patch includes those (as best as I could figure what they
should be) and has been tested to generate valid MIPS crunch
binaries both cross- and native- compiled.
flag immediately so it's only set once per longcal interval.
Without this, the current AR5416 code will continuously spam NF
calibrations during a periodic calibration if the longcal flag
is set. The longcal flag wouldn't be cleared until the calibration
method indicates that calibrations are "complete".
This drops the rate of NF calibration updates down from "once every
shortcal" (ie, every 100ms) during a periodic calibration, to only
once per "longcal" interval. Spamming NF calibrations every 100ms
caused some potentially horrific issues in noisy environments as
NF calibrations can take longer than 100ms and this spamming can
cause invalid NF calibration results to be read back - leading to
missed beacons, and thus leading to a stuck beacon situation.
Stuck beacons cause interface resets, which restart calibrations.
This means that the longcal calibration runs every 100ms (shortcal)
until all initial calibrations are completed. This spamming can then
cause the above issues which leads to stuck beacons, leading to
interface resets, etc, etc. Quite annoying.
Now we use a regular mutex instead of a spin mutex. When we enter and exit
the emulator, spinlock_enter() and spinlock_exit() are additionally used.

32 (this version) 152 MB/s

As read-ahead is heuristic, based on past IO requests, it shouldn't be
problematic. The new default is still smaller then in other OSes.
Add proto spacers to inet6sw like we have for legacy IP. This allows us
to dynamically pf_proto_register() for INET6 from modules, needed by
upcoming CARP changes and SeND.
MC and SCTP could make use of it as well in theory in the future after
upcoming VIMAGE vnet teardown work.

Even though cons25 normally doesn't support origin regions, this
emulator does allow you to do it. It makes more sense to blank only the
origin region when emitting ^L instead of blanking the entire screen.
Apart from that, we should always place the cursor inside the origin
region, which doesn't happen right now.

Linux, NetBSD and DragonflyBSD driver.
While investigating this, it became apparent that the Linux driver always
initialises the device, and not just in the PL2303HX case. Change
uplcom(4) to do the same.
This change allows us to synchronize our device ID list with Linux and
NetBSD, without requiring knowledge of the chipset in use.

- Increase target limit from 4 to 64; this limit will be removed entirely
at a later time.
- Improve recovery from lost network connections.
- Fix some potential deadlocks and a serious memory leak.
- Fix incorrect use of MH_ALIGN (instead of M_ALIGN), which makes no
practical difference, but triggers a KASSERT with INVARIANTS.
- Fix some warnings in iscontrol(8) and improve the man page somewhat.

like memory mapped register access. Typical problem from the issue
was MII access returned unreliable values. I'm not sure this comes
from lack of register flushing in MII access after accessing
STE_PHYCTL register though.
To address the issue, read hints data that controls which type of
memory mapping should be used in driver. ste(4) still prefers
memory mapping to io mapping but honor hints entered by user except
for controllers that have problems with memory mapping.
The hint to use iomapping could be given by adding the following
line to /boot/device.hints file.

However, that was not mention at all, the problem was not reported, the
patch has not been MFCed and the fix is mostly improper.
Fix the original overflow (caused when 32 CPUs must be detected) by
just using a different mathematical computation (it also makes more
explicit the size of operands involved, which is good in the moment
waiting for a more complete support for a large number of CPUs).

- Treat the STICK based timecounter the same way as the TICK based one
regarding its quality and obtaining the counter value from the BSP.
Like the TICK timers the STICK ones also are only synchronized during
their startup (which might not result in good synchronicity in the
first place) but not afterwards and might drift over time, causing
problems when the time is read from different CPUs (see r135972).
