- 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.
SEMMNI, SEMMNS, SEMUME and SHMMAXPGS.
They can be tweaked via sysctl now. Ports that were setting values on
them weren't touched, I only removed the ones that were commented out.
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.

B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.
all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.
XXX: bus_dma(9) needs an update still.
- finish implementing splraiseipl (and makeiplcookie).

- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
Dreamcast does not use SuperH on-chip RTC, so do it seprately from
other sh3 ports. Convert dreamcast rtc code into a real device
instead of searching/attaching it manually.

to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.

The only information to be compensated is text section start address.
The default value is set arch-wise as DEFTEXTADDR. Each kernel config
can override the default value by setting TEXTADDR.
Tested on COMPUTEXEVB (evbsh3).
