kern/linux/linux_system.cc:
    wrote cycle frequency into variable so linux doesn't probe for it.
    The support exists, but it takes two seconds of time to do on a real
    machine, so forever in the simulator.

c9f2aa8c18 Make each stat take up one full line. This allows us to use grep
to find and remove stats from the files so we can put less
burden on the python interpreter.

    Manually insert newlines into the python code so that we now have one
    stat per line.  (Make it so we can use grep -v to remove stats)

9f2aae4e28 Fixes and cleanup to elf loader code.
base/loader/elf_object.cc:
    - Use program header instead of section headers for loading.
    The old code doesn't work for Alpha/Linux user binaries.

    - Deal properly with single-segment ELF executables (e.g. kernels)...
    haven't tested this but it looks like it matches the functionality
    of the patch the L4::Pistachio guys sent.

    - Factor load symbol code into one common function.

    - Some formatting to match style conventions.

    - Only include libelf stuff in .cc file, not .hh.

8384f25620 Check in python script that reads the python stats output.
Still needs a lot of work, but it's at least as good as the
normal output, and has some features that normal ouput is missing
such as bin totalling with correct formulas and totalling of
2d vectors and such.  It will also filter out specific stats
for printing.  (basically grep, but no mistakes.)

510eef0fa0 Modify handling of serialize:dir parameter to make it more useful.
Move global checkpoint-related functions and vars into Checkpoint class (as statics).

    into Checkpoint class (as statics).
sim/serialize.cc:
    Move global checkpoint-related functions and vars
    into Checkpoint class (as statics).

    Checkpoint constructor now takes checkpoint directory name instead
    of file name.

    Make serialize:dir parameter actually set checkpoint directory name
    instead of directory in which checkpoint directory is created.  If
    the value contains a '%', the curTick value is sprintf'd into the
    format to create the directory name.  The default is backwards compatible
    with the old fixed name ("m5.%012d").

7e07aa9300 Fix cprintf bug, plus minor cleanup & better error messages.
base/cprintf.cc:
    Fix bug where a call with a format string with no specifiers
    but one or more arguments would crash.  Old code tried to print
    extra args using last available format, but in this case there
    was no format, hence the problem.  Now we just print "<extra arg>"
    for each extra arg.

    Also reorganized code a bit to make scope of fmt variable
    match the scope in which you can be confident it's meaningful.
