- 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.
to make sure PCI slot 0 interrupt doesn't accidentally match the (unused)
PCI error interrupt.
Fixes kern/25462 at least on my Netra T1 ac200.

XXX Please keep these two in sync as this one is a drop-in replacement
for the sparc version and the idea is to have both sparc and sparc64
use the same file one day.
With this we no longer need machine-dependent code in framebuffer console
drivers and we can use genfb at pci for otherwise unsupported graphics
chips as long as there's firmware support.

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).
sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.
The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).
Update all users and documentation to reflect these changes.
done via locked 4 MB pages. The old format could only record physically
continous kernel text mappings.
For compatibility reasons, just extend the structure and fill in all the
old fields as well.
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.
consistently use uint64_t. Fixes crash dumps on machines with > 2GB
memory. Found by Chris Ross.
While there, remove a #if 0'd part of code that prevented the first
physical memory page to be dumped - I'll solve that differently.
of the corresponding 32bit architecture.
Use it for the 64bit items in netbsd32_statvfs so that the structure
doesn't collect 8byte alignment (and 4 bytes of trailing padding).
This replaces the 'packed' attribute which wasn't architecture specific
and would cause massive overheads accessing every member of sparc64.
Should allow the MIPS64 port do DTRT.
