fb35d474a5 Added code to support setting up all of the auxillieary vectors configured by the sparc linux elf loader.
src/arch/sparc/process.cc:
    All of the auxilliary vectors are now set like they are in the linux elf loader. This code should probably be moved to arch/sparc/linux/process.cc somehow.

19ca97af79 This changeset gets the MIPS ISA pretty much working in the O3CPU. It builds, runs, and gets very very close to completing the hello world
succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!

Anyways, a lot of this stuff had to do with my project at MIPS and me needing to know how I was going to get this working for the MIPS
ISA. So I figured I would try to touch it up and throw it in here (I hate to introduce non-completely working components... )

5639fb2c43 Fix memory leak.
src/arch/alpha/ev5.cc:
    Fix memory leak.  The faults are refcounted, but that only works if you're actually assigning them to a RefCountingPtr.

3e1537cf8b Removed syscall function from thread_context.hh. ThreadContext is the interface for external, non-CPU objects to access the thread, so they probably shouldn't be able to call syscall(). The case it was being used for was already handled by the ISA code.
src/arch/sparc/faults.cc:
src/cpu/thread_context.hh:
    Fix for merge problems.

babb22eea4 Fix python binary name in arch/SConscript.
Also delete no-longer-needed SPARC test.py files (should
have gone with my last chnageset where LiveProcess
became ISA-independent).

src/arch/SConscript:
    Mistakenly committed hard-coded python binary name.
    Should use same python to run isa_parser that was
    used to run scons.
