63bb46b6d8 Serialize the symbol tables
base/loader/symtab.cc:
    Add support for clearing out the symbol table
    Add support for serializing the symbol table (clear on unserialize)
    Don't allow empty symbols to be entered into the table
base/loader/symtab.hh:
    Add support for clearing out the symbol table
    Add support for serializing the symbol table
sim/system.cc:
    Serialize the kernel, console, and palcode symbol tables so that
    we can capture any dynamic symbols that are added and so that we
    don't have to have the same kernel binary around to get the
    symbols right

0dcb288365 Cleanup the StackTrace interfaces and profile interfaces so they
are more efficient and reduce the number of new/delete calls

arch/alpha/stacktrace.cc:
    - Change the StackTrace code so that the class can more easily be
    cleaned out and reused to avoid extra allocations.
    - Allow trace() to accept a static instruction pointer so it can
    determine if the instruction is worth tracing.  This is moved from
    the CPU.
    - provide constants for special meaning PCs (user, console, unknown),
    instead of magic numbers
    - switch to using kernelSymtab instead of allSymtab which will be
    going away
    - if the stack adjustment doesn't make any sense, exit and push
    unknown so we don't get into an infinite loop or record garbage.
    - check to see if we've made too many iterations through the stack
    and panic to avoid an infinite loop
arch/alpha/stacktrace.hh:
    - Change the StackTrace code so that the class can more easily be
    cleaned out and reused to avoid extra allocations.
    - Allow trace() to accept a static instruction pointer so it can
    determine if the instruction is worth tracing.  This is moved from
    the CPU.
    - provide constants for special meaning PCs (user, console, unknown),
    instead of magic numbers
cpu/base.cc:
    only clear the profile if we have one
    include profile.hh here since base.hh doesn't do it anymore
cpu/base.hh:
    no need to include cpu/profile.hh here
cpu/profile.cc:
    use ProfileNode pointers instead of objects in the ChildList
    Consume a vector of addresses since that's really all we
    care about.
cpu/profile.hh:
    Keep pointers to ProfileNodes to reduce the size of these structures
    keep a StackTrace around so that we may reuse it.
    provide consume functions that use the new StackTrace trace interface
    one consume function is inline and tries to fastpath the no trace
    condition, it calls the outlined consume function if a trace is generated.
cpu/simple/cpu.cc:
    include cpu/profile.hh here since base.hh no longer does
    use the new FunctionProfile::consume interface
    (which contains the tracing functions)

e701cf48d9 A couple of FP-related fixes (prompted by Adam having trouble
running SPEC FP codes).

    once per static instruction.  (Had the flag to suppress
    these but forgot to check it!)
build/SConstruct:

    for getting IEEE-compliant FP on x86).

b7b8ffa7b7 Major changes to sinic device model. Rearrage read/write, better
interrupts.

dev/sinic.cc:
    - The prepareRead function sets all the variables in the register
    file that depend on various state bits that change on the fly.
    Includes RxDone, RxWait, TxDone, and TxWait
    - Use the new register information accessor functions to grab
    validity and size information for the read and write functions
    - read all registers directly from the register space by offset
    and size, not by actual name (less code)
    - The side effect of reading the interrupt status (clearing it) now
    happens outside the actual chunk of code where the value is loaded.
    - Add an iprRead function for when we may want speculative access
    to device registers through an ipr or special instruction.
    - When RxData or TxData are written, their busy flag is set to
    indicate that they have an outstanding transaction.
    - The RxHigh and TxLow interrupts are special, they only interrupt
    if the rxEmpty or txFull limits were hit
    - Move reset to the command register
    - Update more registers on reset, clear rxEmpty and txFull
    - Data dumps only happen if EthernetData trace flag set
    - When a DMA completes, kick the other engine if it was waiting
    - implement all of the new interrupts
    - serialize the new stuff
dev/sinic.hh:
    - Put all registers with their proper size and alignment into
    the regs struct so that we can copy multiple at a time.
    - Provide accessor functions for accessing the registers with
    different sizes.
    - Flags to track when the rx fifo hit empty and the tx fifo became
    full.  These flags are used to determine what to do when below
    the watermarks, and are reset when crossing the watermark.
    - the txDmaEvent should actually trigger the txDmaDone function
    - Add an iprRead function for when we may want speculative access
    to device registers through an ipr or special instruction.
    - The prepareRead function sets all the variables in the register
    file that depend on various state bits that change on the fly.
    - add rx_max_intr and dedicated (for dedicated thread) config params
dev/sinicreg.hh:
    Add some new registers: Command, RxMaxIntr, RxFifoSize, TxFifoSize,
    rename XxThreshold to XxFifoMark
    Move Reset to the Command register
    Add Thread to the Config register
    New interrupts, better names
    More info in RxDone and TxDone
    Easier access to information on each register (size, read, write, name)
python/m5/objects/Ethernet.py:
    Both sinic and nsgige have the dedicated thread
    Add a parameter to configure the maximum number for receive
    packets per interrupt
