simplify and make complete some asi checks implement all the twin asis and remove panic checks on their use soft int is supported, so we don't need to print writes to it src/arch/sparc/asi.cc: make AsiIsLittle() be all the little asis. Speed up AsiIsTwin() a bit src/arch/sparc/faults.cc: clean up the do*Fault code.... Make it work like legion, in particular pstate.priv is left alone, not set to 0 like the spec says src/arch/sparc/isa/decoder.isa: implement some more twin ASIs src/arch/sparc/tlb.cc: All the twin asis are implemented, no need to say their not supported anymore src/arch/sparc/ua2005.cc: softint is supported now, no more need to --HG-- extra : convert_revision : aef2a1b93719235edff830a17a8ec52f23ec9f8b
