5a1340d046 Another fix for the too much work problem in 2.6. This should do it.
Both rx/tx interrupts are now scheduled for the future to give the
linux kernel time to get out of its loop.

38fe4d9a86 With the new uart code 300 cycles isn't quite enough, 350 seems to
work. When everything gets changed to seconds this should be updated.

838273a196 fix up the recordEvent stuff to support ignoring events
arch/alpha/ev5.cc:
cpu/simple_cpu/simple_cpu.cc:
    update for new event interface
base/stats/events.cc:
    implement the ignore event function which matches sim objects from which
    to ignore events.

    Make insert event like insert data and make it able to insert many
    events in a single transaction with the database.
base/stats/events.hh:
    Make it possible to ignore events
sim/sim_object.cc:
    make recordEvent a member function of SimObject to implement
    the ignore function easily
sim/sim_object.hh:
    implement the ignore event stuff in the sim object.  This is a
    bit of a hack, but an easy place to put it.

c1e58b6bf6 Handle SIGABRT a little more nicely.
base/misc.cc:
    Don't dump trace in panic(), SIGABRT handler will do it now.
sim/main.cc:
    Add SIGABRT handler that prints curTick and dumps buffered trace (if any).
    This doesn't work as well as I would like since the buffered trace records
    often contain stale references to stack-resident temporary std::string objects.
    Someday we'll have to put in a fix for that.

4c2f38fade Record execution faults in DynInst fault field. Previously the
DynInst field was being set only on memory faults.  If an FP
memory op encountered an FP enable fault, then the bogus memory
op would still get processed since the pipeline relied on the
inst->fault field to tell if the op was bogus.

base/traceflags.py:
    added some more traceflags for ethernet to break it up better
dev/etherpkt.hh:
    since we are not network host order, must reverse bytes for these typechecks.

    also, overload isTcp/UdpPkt to take an argument so you don't have to reget the ip header if you've already got one.
dev/ns_gige.cc:
    1) add some functions that reverse Endianness so we can generate adn evaluate checksum adn dprintf data accurately/more understandably

    2) forget about the implementation of fifo fill/drain thresholds, it's not used by the driver much, nor does it matter with use sending/receiving in whole packets anyway.
    get rid of teh associated variables.

    3) get rid of txFifoCnt the variable, it's redundant and unnecessary, just use txFifoAvail.

    4) change io_enable to ioEnable, just to be picky.

    5) modify some DPRINTF's to be clearer, also added a lot, and spread them into better traceflag categories

    6) fix the device bug!  it's the intrTick = 0 at teh beginning of cpuInterrupt().

    7) clear some bools in regsReset() so they don't holdover wrong state

    8) fix pseudo header generation for Tcp checksumming to account for network order
dev/ns_gige.hh:
    change io_enable to ioEnable, get rid of fill/drain thresh related variables and txFifoCnt, which is redundant
