1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.
ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.
the original ad-audiomp branch notes:
Add MP locking to the audio drivers.
Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.
The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.
Welcome to 5.99.57.
especially on RTL8019AS which is also used for non-ISA local bus of
embedded controllers and some m68k machines like atari and x68k.
* move RTL8019 probe and attach code from each bus attachment
to MI ne2000_detect() and ne2000_attach()
* change a method for backend and attachment to specify 8 bit mode
to use a new sc->sc_quirk member, instead of sc->sc_dmawidth
* handle more NE2000 8 bit mode specific settings, including
bus_space(9) access width and available size of buffer memory
* add a function to detect NE2000 8 bit mode
(disabled by default, but enalbed by options NE2000_DETECT_8BIT
to avoid possible regression on various ISA clones)
* fix ipkdb attachment accordingly (untested)
Tested on two NE2000 ISA variants (RTL8019AS and another clone named UL0001)
in both 8 bit and 16 bit mode on i386. "Looks good" from nonaka@.

There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
