318e0c93ed add support for simple character input via the system console
dev/alpha_access.h:
    -  use our standard types instead of this extra typedef
    -  advance the ALPHA_ACCESS version since the interface
    has changed.  *this means you need a new console binary*
    -  shuffle a couple things around to pack the data structure
    a bit better
    -  add a placeholder for character input
dev/alpha_console.cc:
    Clean up the read code path a bit and add support for character
    input via the console

    Clean up the write path and use a switch instead of a bunch of
    if statements

d5a187dd5a Miscellaneous minor fixes/improvements.
Most notable is that the rundiff trace-output lossage is fixed!

base/pollevent.cc:
    Use SA_RESTART to keep blocked write() calls from failing
    with EINTR when signals happen.
base/trace.hh:
    Make TRACING_ON depend on NDEBUG not being set (instead of
    DEBUG being set) so m5.opt/m5.fast do what we want.
util/rundiff:

2cd5e980d2 Fixes for full-system call_pal instruction.
arch/alpha/alpha_memory.cc:
    Rename md_mode_type to mode_type.
arch/alpha/ev5.cc:
    simPalCheck() only gets called on correct path now, so
    there's no need to test misspeculating().
arch/alpha/isa_desc:
    Get privileged call_pall detection right this time (I hope).
    ExecContext::simPalCheck() and Annotate::Callpal() are now
    called only on non-speculative executions... this should fix
    the bogus pal-call stats we've been seeing (since these are
    incremented in simPalCheck()).
    Also check for invalid call_pall function codes.

777c1ebfab Stats & serialization tweaks & cleanup. Unserializing from
a checkpoint now gives identical results to running from scratch
and doing at switchover at the same cycle!
- CPUs start at cycle 0 again, not cycle 1.
- curTick is now serialized & unserialized.
- Stats get reset in main (before event loop).  Since this is done
after curTick is unserialized, simTicks gets set correctly for
running from a checkpoint.
- Simplify serialization to happen in a single pass.

368de4109f Sweeping change in the stats package....again...
base/statistics.cc:
    -  Merge the m5 display and simplescalar compatible display functions.
    -  Use functors for the stats printing instead of functions.  This
    gets rid of the very long argument lists and improves clarity.
    -  Fix a bug in binning that caused an invalid allocation to occur.
base/statistics.hh:
    -  Instead of using a compile time variable to choose whether
    to print in ss compat mode, we use a runtime variable.
    This is how we'll choose python output.
    -  There are no more virtual functions in the statistics themselves.
    All virtual functions have been moved into a secondary helper class.
    Every stat has an associated helper class that knows how to access
    certain variables in that stat.
    There is a hash_map from the stat to it's helper class data.  This was
    done because the helper data is only used during setup, stats reset,
    and printing.  All of which happen rarely, and you want to avoid
    any performance hit that you can.
    -  To provide the name(), desc(), etc functions to classes so that the
    user can set various parameters to the stats class, a single class
    containing all of those functions was created.  An odd trick was
    done to actually make this class derive from the stat class because
    a base class with no data actually does end up taking up space.
    -  The detail namespace was removed for now.  I'll put it back when the
    package is not in so much flux.
    -  Standard deviation, and mean were added to all distribution stats.
    -  There are several bugfixes and changes that aren't mentioned
test/Makefile:
    Don't test sim_stats foo.
test/stattest.cc:
    Don't test sim_stats foo.
    Fix bin usage so that it corresponds to the current usage.

1d7c11af7d Instead of keeping track of the fraction of time that we're
idle, keep track of the fraction of time we're not idle.  This
works better because the default processor state is idle, and
the default stat value is 0.
Keep the stat as idleFraction which is a formula that is equal
to 1 - notIdleFraction
