Pull up following revision(s) (requested by martin in ticket #547):
        sys/arch/sparc64/sparc64/pmap.c: revision 1.188
        sys/arch/sparc64/include/ctlreg.h: revision 1.43
When invalidating a context, make sure to flush user windows upfront.
Do not set the DMMU secondary context to 0 (that would be kernel), and
add a few required membars after switching the secondary dmmu context.
This avoids SIRs caused by double kernel_data_faults, caused by spills
of obsolete user windows after the context for that user pmap is gone.
