Move some common full-system CPU initialization from the
SimpleCPU & FullCPU constructors to AlphaISA::initCPU(). cpu/simple_cpu/simple_cpu.cc: Move some common full-system CPU initialization from the SimpleCPU & FullCPU constructors to AlphaISA::initCPU(). Make 'fault' local to SimpleCPU::tick. cpu/simple_cpu/simple_cpu.hh: Make 'fault' local to SimpleCPU::tick (not an object member). --HG-- extra : convert_revision : e878dedfff06aac0548aca8b14d66c18b8916895
