Deal with block initializing stores (by doing nothing, at some point we might want to do the write hint 64 like thing)
Fix tcc instruction igoner in legion-lock stuff to be correct in all cases
Have console interrupts warn rather than panicing until we figure out what to do with interrupts
src/arch/sparc/miscregfile.cc:
src/arch/sparc/miscregfile.hh:
add a magic miscreg which reads all the bits the tlb needs in one go
src/arch/sparc/tlb.cc:
initialized the context type and id to reasonable values and handle block init stores
src/arch/sparc/tlb_map.hh:
fix bug in tlb map code
src/base/range_map.hh:
fix bug in rangemap code and add range_multimap
(these are probably useful for bus range stuff)
src/cpu/exetrace.cc:
fixup tcc ignore code to be correct
src/dev/sparc/t1000.cc:
make console interrupt stuff warn instead of panicing until we get interrupt stuff figured out
src/unittest/rangemaptest.cc:
fix up the rangemap unit test to catch the missing case
