Fixes for full system compiling.
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. --HG-- extra : convert_revision : a8bbf562a277aa80e8f40112570c0a825298a05c
