93b3176d4e Fixed the priv instruction format.
src/arch/sparc/isa/formats/priv.isa:
    Fix the priv format so that it uses isa_parser operands rather than accessing the registers directly in checkCode. Also, the expressions needed to be negated.
src/arch/sparc/isa/operands.isa:
    Added an Hpstate operand, and adjusted the numbering.

e2eef8859b Implemented the SPARC fill and spill handlers.
src/arch/sparc/faults.cc:
src/arch/sparc/faults.hh:
    Added a function to do normal SPARC trap processing, and implemented the spill and fill faults for SE
src/arch/sparc/process.cc:
src/arch/sparc/process.hh:
    Added fill and spill handlers which are stuffed into the processes address space. The location of these handlers are stored in fillStart and spillStart.

5e2263fc52 Small bug fixes for timing LL/SC. Better now but
not necessarily 100% there yet.

    Clear packet flags when reinitializing.
    (SATISFIED in particular is one we don't want to leave set.)
