        src/sys/arch/sparc64/include: ctlreg.h
        src/sys/arch/sparc64/sparc64: pmap.c

Log Message:
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.
