Sprinkle pmap_update() calls after calls to:
...
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).
These calls are relatively conservative. It may be possible to
optimize these a little more.

Split cpu from mainbus so that cpu can attached to other buses (like ofbus).

Put back that old (not) unused include file. But only include it
...
when ARMFPE is defined. Since that is the only time we use it.

Change the value of tf_pc in undefined-instruction handlers on arm32. It now
...
always points to the undefined instruction in question. It's up to the
handler to advance it to the next instruction if it wants execution to
continue there. This is how things have always worked on arm26.

Update FPU detection to use remove_coproc_handler().

Pass a softc pointer around everywhere, and use it when we need the name of
...
the device.
Don't pretend that fpe0 and fpu0 exist as devices (they don't).
G/C a few items related to /dev/cpu* support.

Add code to point out to the user if their CPU isn't supported, and to
...
suggest what kernel options to use to get it to work.

Change the meaning of cpu_class. It now has one value for each core we
...
support, which corresponds to one for each CPU_* option, or one for each
cpufunc structure.
Also remove some more residual code for the support of multiple and non-ARM
CPUs.

Add CPU ID for ARM7500FE (determined empirically from two I've got here).

Kill cpu_host and cpu_flags: they weren't having any practical effect.

Remove support for /dev/cpu*. This code has never done anything useful anyway.

Remove spurious declaration of initialise_fpe().

NCPU will always be 1 if this file is being compiled at all, so don't bother

checking it.

Re-design identify_arm_cpu() to use a table of CPU types. This also makes
...
it easy for it to identify lots of CPU types, so have it do that too.

Fix up indentation, and remove a spurious set of braces. Should be no

semantic change from the last revision.

fpe-sp, and the associated "options FPE", was deleted in 1997. G/C references

to it.

Move arm32 ports over to using <arm/armreg.h>, so <cpu.h> mostly contains
...
NetBSD-specific definitions.
This also entails some changes to the way CPU identification is done. I hope
I've got it right.

The cpu_type element of struct _cpu was only used in identify_arm_cpu().
...
Make it a local variable.

Part 2 of merge.... the dissapearance of mainbus from arm32 and hpcarm;

these parts were a 100% the same and i've included the extensions made by
hpcarm in the tree.
Checked for occurence of MD parts; none found.
