Modified Files:
        syssrc/sys/arch/sh5/sh5: process_machdep.c

Log Message:
Add a hack at the end of setregs() which works around a bug which can,
under some circumstances, leave turds in the icache following vmspace
teardown.

It's not yet clear if this is a pmap bug or a toolchain problem since
the hack is unecessary when the kernel is compiled with -O0. Of course
that could just be masking the problem due to increased icache pressure...
