Changes to make m5ops work under virtualization seemed to break them working
with non-virtualized systems and the recently added m5 fail command makes
the m5op binary not compile. For now remove the code for virtualization.
In order to support m5ops in virtualized environments, we need to use
a memory mapped interface. This changeset adds support for that by
reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR
interface for m5ops. The mapping is done in the
X86ISA::TLB::finalizePhysical() which means that it just works for all
of the CPU models, including virtualized ones.
Used as a command in full-system scripts helps the user ensure the benchmarks have finished successfully.
For example, one can use:
/path/to/benchmark args || /sbin/m5 fail 1
and thus ensure gem5 will exit with an error if the benchmark fails.
The number of arguments specified when calling parse_int_args() in
do_exit() is incorrect. This leads to stack corruption since it causes
writes past the end of the ints array.
Usage: m5 writefile <filename>
File will be created in the gem5 output folder with the identical filename.
Implementation is largely based on the existing "readfile" functionality.
Currently does not support exporting of folders.

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.

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

Convert atoi to strtoul so that we can use 64bit numbers and even
