2484aeaee7 Minor changes to Time
base/time.cc:
base/time.hh:
    Don't set the current time in the constructor.  Use a flag and
    make the default to not set the time.
    Change reset() to set().  Dunno.  Just seems right.

ea604923aa Update to store uncompressed data in the cache blocks at all times. This will allow us to simulate compression without paying the uncompress penalty on reads.
This also had the side-effect of getting copies and compression working together (collecting of code in helper function made this easier.)

f3861d0cc7 Overall gist of this is to 'dynamicize' the tracking of functions so you can choose them at the .ini stage rather than at compile time.
to do it:
in .ini file set binned_fns=foo null bar foo

what this says is, track foo when it is called by null (i.e. anything).  bin bar only when it is called by foo.
essentially, if you have a path of functions to track, the 0th, 2nd, 4th fn listed are the fns to track, and the 1st, 3rd, 5th are their respective callers.

base/statistics.hh:
    turn it back to FS_MEASURE since we already have a build in place
kern/tru64/tru64_events.cc:
    remove FS_MEASURE #defs.  add more DPRINTF's.  manage an anomaly that happens when tracking idle_thread.
kern/tru64/tru64_events.hh:
    remove FS_MEASURE #defs
kern/tru64/tru64_system.cc:
    make DumpState print all the time, but only with DPRINTF.  add a new parameter to tru64System a vector<string> binned_fns, to read in from .ini file.  now all this binning stuff is dynamically generated.
kern/tru64/tru64_system.hh:
    remove all static binning stuff, add support for dynamic
sim/system.cc:
    change nonPath bin name to Kernel, remove FS_MEASURE
sim/system.hh:
    change nonPath to Kernel

b05d7f99ac Make sure to arbitrate for the payload bus in the header splitting case,
and to free up the header bus by returning false.  If there is no
header splitting it will work normally.
