c8a2d602b1 do a linear search for matching tlb entries instead of using map because you could be mapping a larger page that intersects many
fix for lookup table to keep it consistant with tlb on a replace of a specific entry

ecfd628ecd Modify ISA and staticInst to support a IsFirstMicroOp flag
Increment instruction count on first micro-op instead of last

src/arch/sparc/isa/decoder.isa:
    Implement a twin load for ASI_LDTX_P(0xe2)
src/arch/sparc/isa/formats/mem/blockmem.isa:
    set the new flag IsFirstMicroOp when needed
src/cpu/simple/atomic.cc:
    Increment instruction count on first micro-op instead of last (because if we take a fault on a micro coded instruction it should be counted twice acording to legion)
src/cpu/static_inst.hh:
    Add IsFirstMicroop flag to static insts

9d04510869 bug fixes to get us to 145m instructions
src/arch/sparc/intregfile.cc:
    some checks to make sure that the cwp and global register flattening stuff is working. These things have caught a couple of bugs so I think it would be good to keep them around at least for now
src/arch/sparc/isa/decoder.isa:
    fix smul instruction to write Y correctly
src/arch/sparc/miscregfile.cc:
    legion always returns du and dl set, so we need to emulate that for now at least

a8b2d66661 change when legion-lock causes the simulation to die. It now happens after two consuctive differences since we compare stuff
at slightly different times interrupts are seen the cycle before they happen in m5 so the pc gets changed early.
