Remove unnecessary <sys/malloc.h>.

Fix locking after opendisk(), VOP_IOCTL() needs an unlocked vnode,
vn_rdwr() needs flag IO_NODELOCKED.

sys: Fix various abuse of struct device internals.

Will help to make struct device opaque later.

fix proplib deprecation

branches: 1.13.12;
Fix attach failure of zaudio(4) WM8731 (C7x0/860) and WM8750 (C1000/3x00).

The new MI iic(4) layer requires an explicit quirk info of PROBE_STRATEGY
via device properties. Fixes PR kern/54658.

Should be pulled up to netbsd-9.

branches: 1.12.40; 1.12.44;
Do not call setroot() from MD code and from MI code, which has
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

Make detection of root on wedges (dk(4)) machine independent. Remove
MD code for zaurus.

Don't check device numbers.

branches: 1.9.4; 1.9.6;
Use deviter(9) instead of accessing alldevs directly. Untested.

Added kloader support.

Added zboot from OpenBSD.

Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

branches: 1.4.2;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.3.2; 1.3.4; 1.3.6;
Added support to detect AC adapter and charge battery.
