73dd0ea357 Instead of passing an int to represent time between python and C++
pass the tuple of python's struct_time and interpret that.
Fixes a problem where the local timezone leaked into the time
calculation.  Also fix things so that the unix, python, and RTC
data sheets all get the right time.  Provide both years since 1900
and BCD two digit year.
Put the date back at 1/1/2006 for now.

overwrite the register we are using for address calculation
only erase a entry from the lookup table if it's valid

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
