See configs/test.py for test config (using simple
binary in my home directory on zizzer).
base/chunk_generator.hh:
Fix assertion for chunkSize == 0 (not a power of 2)
base/intmath.hh:
Fix roundDown to take integer alignments.
cpu/base.cc:
Register exec contexts regardless of state (not sure why
this check was in here in the first place).
mem/physical.cc:
Add breaks to switch.
python/m5/objects/BaseCPU.py:
Default mem to Parent.any (e.g. get from System).
python/m5/objects/Ethernet.py:
python/m5/objects/Root.py:
HierParams is gone.
python/m5/objects/PhysicalMemory.py:
mmu param is full-system only.
sim/process.cc:
Stack mapping request must be page-aligned and page-sized.
Don't delete objFile object in create since we are counting
on it being around for startup().
