1511370d09 More progress on checkpointing... we can now write out a checkpoint and read it back in,
though most objects don't actually serialize any data.

a0f3ee7e17 Add a few configuration DPRINTFs.
Fix handling of chars (uint8_ts) in serialization.
Minor cleanup.

sim/param.cc:
    Add specialization of showParam for char: output as ints, not as characters.
    Clean up comments a bit.

3761bcf076 Get new serialization code to link.
sim/param.cc:
    Convert parseParam() and showParam() to templates,
    andd explicitly instantiate them for common types.
sim/param.hh:
    Add declarations for parseParam() and showParam() function templates,
    so serialize.cc can use them.
sim/serialize.cc:
    Don't need declarations for parseParam() and showParam() since
    we put them in param.hh.
    Also instantiate paramOut() etc. for bool.

91cb532f9f Make FullCPU schedule its TickEvent when one of its contexts becomes active.
This fixes detailed-mpboot, which was broken as of my last change.
Also clean up some of the ExecContext status initialization.

cpu/base_cpu.hh:
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
    BaseCPU::registerExecContexts() no longer needs to be virtual.
cpu/exec_context.cc:
    Initialize _status directly... don't use setStatus() as this will notify the CPU
    of the change before it is ready.
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
cpu/exec_context.hh:
    Don't need initStatus() any more.
cpu/simple_cpu/simple_cpu.cc:
    Move execCtxStatusChg() from header to .cc file.
    No longer need specialized version of registerExecContexts to schedule TickEvent.
cpu/simple_cpu/simple_cpu.hh:
    Move execCtxStatusChg() from header to .cc file.
    CPU::execCtxStatusChg() now takes thread_num as arg (must be 0 for SimpleCPU).
    No longer need specialized version of registerExecContexts to schedule TickEvent.
kern/tru64/tru64_system.cc:
    Don't need initRegs; the PC etc. get initialized in the CPU constructor.
    ExecContexts start out as Unallocated, so no need to set them to Unallocated here.
kern/tru64/tru64_system.hh:

f5da73b688 Initial support for CPU switching. New SamplingCPU object encompasses a set
of CPUs that get switched round-robin (though currently we're only shooting for
two CPUs and one switch event, and even that doesn't quite work yet).  Registration
of ExecContexts with System/Process object factored out so we can create two CPUs
but only register one of them at a time.  Also worked at making behavior and naming
in System and Process objects more consistent.
