Fix some unset values in the request in the timing CPU.
Properly implement the MSHR allocate function. src/cpu/simple/timing.cc: Set the thread context in the CPU. Need to do this properly, currently I just set it to Cpu=0 Thread=0. This will just cause all the stats in the cache based on these to just yield totals and not a distribution. src/mem/cache/miss/mshr.cc: Properly implement the allocate function for the MSHR. --HG-- extra : convert_revision : bcece518e54ed1404db3196f996a77b4dd5c1c1e
