Merge ktlim@zizzer:/bk/m5

into  zamp.eecs.umich.edu:/z/ktlim2/m5-proxyxc

Further changes still need to be made to the XC code.

arch/alpha/ev5.cc:
arch/alpha/freebsd/system.cc:
arch/alpha/linux/system.cc:
base/remote_gdb.cc:
cpu/cpu_exec_context.cc:
cpu/cpu_exec_context.hh:
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
kern/kernel_stats.cc:
sim/pseudo_inst.cc:
    Hand merge.
