Set locked flag if required
make SC always return success -- this needs to be fixed at some point
fix a couple of things
FS executes a bit of console code before dying a horrible death
arch/alpha/linux/system.cc:
only need to copy the length of the os flags param, not 256 bytes
cpu/simple/cpu.cc:
Set the physical flag if required
Make LL/SC always return success
mem/bus.cc:
add some dprintfs and change a assert to a panic
mem/port.cc:
delete the buffer with the [] operator
mem/request.hh:
add a function to reset a request

Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).
There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.
SConscript:
Add compilation support for request.cc

Update for unified request object and accessor functions.
mem/request.hh:
Remove CpuRequest, make it a unified object. Make variables private with accessor functions.
May want to move things from .cc file into header (usually a assert() and either returning a value, or writting two).

Ignoring returned latency for now.
Refactored loadSections in ObjectFile hierarchy.

base/loader/object_file.hh:
Have each section record a pointer to image data.
This allows us to move common loadSections code into ObjectFile.
base/loader/object_file.cc:
Have each section record a pointer to image data.
This allows us to move common loadSections code into ObjectFile.
Also explicitly load BSS now since we need to allocate the
translations for it in syscall emulation.
cpu/base.hh:
Don't need memPort (just pass port in to ExecContext constructor).

mem/translating_port.hh:
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.
cpu/simple/cpu.cc:
Explicitly choose one of three timing models.
Statically allocate request and packet objects when possible.
Several more minor bug fixes.
Works for simple program with SIMPLE_CPU_MEM_IMMEDIATE model now.
Probably have memory leaks with SIMPLE_CPU_MEM_TIMING (if it works at all).
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.
cpu/simple/cpu.hh:
Explicitly choose one of three timing models.
Statically allocate request and packet objects when possible.
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.

Set packet result field.

Clean out old memory python files, move them into old_mem directory. Maybe we should just delete them, they are under revision control.
Add new py files for new objects.
SConscript:
Update because memory is just a header file now
base/chunk_generator.hh:
Make Chunk Generator return the entire size if the chunk_size is set to zero. Useful when trying to chunck on blocksize of memory, which can write large pieces of data.
cpu/simple/cpu.cc:
Make sure to delete the pkt.
mem/physical.cc:
mem/physical.hh:
Set up response event.
mem/port.cc:
Rename rqst to req to conform to same standard naming convention.
python/m5/objects/PhysicalMemory.py:
Update the params, inheritence

After seeing how this gets used in practice, the
send/recv*Query names just don't make a lot of sense.

clean up implementation a little.
SConscript:
Add mem/port.cc
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
Move read/writeBlob functions to base Port class.
mem/port.hh:
Implement read/writeBlob functions.
No need for them to be virtual since the proxy
object (now called TranslatingPort) is not a
subclass of Port.
mem/port.cc:
Implement read/writeBlob functions.
