Minor style fixes to asm codes. No binary changes.

Sync with HEAD.

For Explora 451, call calc_delayconst() before pckbc_cnattach(), which
depends on delay() and DELAY().

Unfortunately, proplib(9) API is not available for MD codes, that are
called before consinit() (since pool(9) is not initialized yet).

Therefore, hard-code CPU frequency to calc_delayconst() in case
"processor-frequency" is not initialized.

Invoke hardclock() and statclock() in the interrupt context.

Otherwise, entropy_enter() is used instead of entropy_enter_intr() in
statclock(), which results in KASSERT() failure.

Simplify and correct stale comment; nticks-th hardclock() had no longer
been special since rev 1.24:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/powerpc/ibm4xx/clock.c#rev1.24

No functional changes intended.

Include missing opt_ppcarch.h.

For struct timecounter, use C99 initializers.
Compile tested. No functional changes intended.

merge to -current.

Reenable interrupt before was call pic_do_pending_int() by splx(), or KASSERT().

Catchup with rmind-uvmplock merge.

Change IBM4xx to use the common powerpc PIC framework.
Consolidate most ibm4xx initppc function into ibm4xx_init
and Make all IBM4xx use it.
Change explora to use initppc instead of bootstrap.

Use <sys/foo.h> instead of <machine/foo.h> if such a file exists.
Don't assume <sys/cpu.h> includes <powerpc/subarch/cpu*.h>.  Include it
explicitly.

Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.

Deal with new powerpc world.

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>.

Make sure we mask statclock timer on ibm4xx systems. This avoids
pthread "related" panics like:

    panic: remrunqueue: bit 18 not set

While there, cleanup IPL_ definitions somewhat and fix interrupt mask
calculation per spl(9).

Merge from HEAD.

Bring ibm4xx interrupt code up to date:

- generic soft interrupts (ie. use powerpc/softintr.c)
- interrupt event counters (using the ones from powerpc/cpu.h:cpu_info
  where appropriate)
- cleanup ibm4xx_intr.h, move implementation details to intr.c

Convert all affected evbppc platforms.

OK by simonb@, some points discussed with matt@

Remove the devprop API and switch everthing over to the new proplib.  Add
a new device_properties() accessor for device_t that returns the device's
property dictionary.

A more accurate microtime() implementation.  Avoids precision

__KERNEL_RCSID()

Add support for the IBM 403GCX cpu. Enabled with "options PPC_IBM403".

  - different set of device control registers.
  - non-standard access to the time base.
  - 16 byte cache lines.

Don't need <machine/walnut.h> here.

Don't frob cpu-specific DCR registers in common code.

Catch up with powerpc rototilling.

move more inlines to cpu.h: mftb(), mftbl() and mfpvr().
(the mftb() in pmap.c only wanted the lower 32 bits, so that's now mftbl()).

Sprinkle a small amount of KNF.

Use properties instead of board_info.

This should be pretty standard.
