arch/alpha/arguments.cc:
There will not be a phys mem ptr in the XC in the newmem. This read will have to go through something else.
arch/alpha/ev5.cc:
Remove instantiations of these functions for the FastCPU, as the FastCPU is not really used. Also this messed up the ability to specify which CPU models are being built.
cpu/exec_context.hh:
Remove getPhysMemPtr() function.
cpu/exetrace.cc:
Include sim/system.hh, and sort the includes.
cpu/simple/cpu.cc:
Fixes for full system compilation.
kern/system_events.cc:
Remove include of encumbered FullCPU. The branch prediction will need to be fixed up in a more generic way in the future.
