26d7b5a4d1 Add quiesceNs, quiesceTime, quiesceCycles, and m5panic pseudo ops.
This changeset removes a check that prevents quiescing when an
interrupt is pending. *** You should only call quiesce if that
isn't a problem. ***

arch/alpha/isa/decoder.isa:
sim/pseudo_inst.cc:
sim/pseudo_inst.hh:
    Add quiesceNs, quiesceCycles, quisceTime and m5panic pseudo ops.
    These quiesce for a number of ns, cycles, report how long
    we were quiesced for, and panic the simulator respectively.
    The latter is added to the panic() function in the console and linux
    kernel instead of executing an infinite loop until someone notices.
cpu/exec_context.cc:
cpu/exec_context.hh:
    Add a quiesce end event to the execution contexted which upon
    executing wakes up a CPU for quiesceCycles/quiesceNs.
util/m5/Makefile:
    Make the makefile more reasonable
util/m5/m5.c:
    update the m5op executable to use the files from the linux tree
util/m5/m5op.S:
    update m5op.S from linux tree
util/m5/m5op.h:
    update m5op.h from linux tree

1cd3757db9 add several new functions that can be called from the guest
to tell the simulator to do something.
exit -> exit_old (deprecated
exit now takes an optional parameter that tells it to execute at a
specified time in the future

The next four functions have two optional parameters.  The first
specifies a delay for how long to wait to issue the instruction.
The second will tell the simulator to repeat that command
at the specified interval.

checkpoint will trigger a checkpoint
dumpstats will cause the simulator to dump stats
resetstats will cause all stats to be reset
dumpreset will dump and reset stats


all times are in nanoseconds

util/m5/Makefile:
    Clean up to make it a bit easier to muck with
util/m5/m5.c:
    Add a bunch of new commands and clean up the command parsing path
    Convert atoi to strtoul so that we can use 64bit numbers and even
    hex if we want to.  (this runs on alpha, so a long is 64bit)
util/m5/m5op.h:
    add prototypes for new m5 instructions
    use uint64_t since it's nicer

15613161c2 Commit a command for use inside a simulated system for communicating
with the simulator.  This program is generally compiled as the name
m5 and installed in /usr/local/bin

This command uses opcodes that are invalid on a normal system, so
don't expect it to do anything on a real system.
