Fix up kernel stats, allow them to not be used as well.
arch/alpha/ev5.cc: Fix up some stuff I missed in the last kernel stats checkin. cpu/checker/cpu.cc: Allow the checker to disable its kernel stats. cpu/cpu_exec_context.cc: Allow CPUExecContext to be created without kernelStats. cpu/cpu_exec_context.hh: Allow CPUExecContext to be created without kernelStats. Default usage leaves kernelStats on. --HG-- extra : convert_revision : 8ed5bffd3a5b6275baa07fb4ea385eeab1a0456a
