Log Message:
Re-do the following revisions, this time on a branch where they won't
interfere with the nathanw_sa merge:

syssrc/sys/arch/arm/arm32/cpuswitch.S			1.26
syssrc/sys/arch/arm/arm32/genassym.cf			1.18
syssrc/sys/arch/arm/arm32/vm_machdep.c			1.21

Original commit message:

In cpu_switch(), stack more registers at the start of the function,
and hence save fewer into the PCB.  This should give me enough free
registers in cpu_switch to tidy things up and support MULTIPROCESSOR
properly.  While we're here, make the stacked registers into an
APCS stack frame, so that DDB backtraces through cpu_switch() will
work.

This also affects cpu_fork(), which has to fabricate a switchframe and
PCB for the new process.
