Fix the packet data allocation methods. Small fixes from changesets after my initial work.
This now compiles. src/mem/cache/base_cache.cc: Fix getPort function that changed src/mem/cache/base_cache.hh: Fix get port function, provide default implementations of virtual functions in the base class src/mem/cache/cache.hh: Fix virtual function declerations src/mem/cache/cache_builder.cc: Fix params src/mem/cache/cache_impl.hh: src/mem/cache/miss/blocking_buffer.cc: src/mem/cache/miss/miss_queue.cc: src/mem/cache/miss/mshr.cc: src/mem/cache/prefetch/base_prefetcher.cc: src/mem/cache/tags/iic.cc: src/mem/cache/tags/lru.cc: Properly allocate data in packet --HG-- extra : convert_revision : dedf8b0f76ab90b06b60f8fe079c0ae361f91a48
