Have you always executed an eieio or sync when you get here, or
do you just not allow direct access to I/O devices? Other context
synchronising insns are not enough, they do not broadcast on the
bus.
There is no device passt

You can also get application with hand-coded cache optimizations

There are generic parts of PowerPC that can be shared across all
implementations and specific parts that only apply to BookE or desktop PPCs.
This patch adds emulation for desktop specific opcodes that don't apply
to BookE CPUs.
