malloc(9) -> kmem(9)

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

Move things around for <arm/arm32/machdep.h>

Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch
from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded
includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.

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.

Remove all references to spl_mask. Now it isn't used by any sources.
Discussed on port-arm.

KNF. Correct some spelling errors.

remove irqblock[] as no one uses it. reviewed by Ben Harris.

Dump IRQ handlers only when INTR_DEBUG is defined, it's to verbose for DEBUG.

Use ANSI function decls.

Centralize ARM CPU configuration information by adding a new header
file, <arm/cpuconf.h>, which pulls in "opt_cputypes.h" and then defines
the following:
* CPU_NTYPES -- now many CPU types are configured into the kernel. What
you really want to know is "== 1" or "> 1".
* Defines ARM_ARCH_2, ARM_ARCH_3, ARM_ARCH_4, ARM_ARCH_5, depending
on which ARM architecture versions are configured (based on CPU_*
options). Also defines ARM_NARCH to determins how many architecture
versions are configured.
* Defines ARM_MMU_MEMC, ARM_MMU_GENERIC, ARM_MMU_XSCALE depending on
which classes of ARM MMUs are configured into the kernel, and ARM_NMMUS
to determine how many MMU classes are configured.

Remove the needless inclusion of "opt_cputypes.h" in several places.
Convert remaining users to <arm/cpuconf.h>.
