e2c7618e50 This patch pulls out the auxiliary vector struct from individual ISA
LiveProcesses to the base LiveProcess definition so anyone can use them.

67fda02dda Make it so that all thread contexts are registered with the System, even in
SE.  Process still keeps track of the tc's it owns, but registration occurs
with the System, this eases the way for system-wide context Ids based on
registration.

8ea5176b7f arch: TheISA shouldn't really ever be used in the arch directory.
We should always refer to the specific ISA in that arch directory.
This is especially necessary if we're ever going to make it to the
point where we actually have heterogeneous systems.

9b49a78cfd Address translation: Make the page table more flexible.
The page table now stores actual page table entries. It is still a templated
class here, but this will be corrected in the near future.

e410a925df X86: Start implementing segmentation support.
Make instructions observe segment prefixes, default segment rules, segment
base addresses.
Also fix some microcode and add sib and riprel "keywords" to the x86
specialization of the microassembler.

4af5740afd X86: Finally get the x86 initial stack frame right.
After very carefully reading through the Linux source, I'm pretty confident I now know -exactly- how the initial stack frame is constructed, filled, and aligned.

4b29d22386 X86: Get rid of initialization of R11
R11 is just junk after the start of exectuion because we're "returning" from
an execve call and linux destroys the contents of rcx and r11 on system calls.

5e34c62b3b X86: Initial stack frame fixes and constant shuffling.
The initial stack frame for x86 is now substantially more correct. The fixes made here can be back ported to SPARC and possible the other ISAs as well. The auxiliary vector types were moved to the LiveProcess base class because they are independent of ISA. Some of the types may only apply to Linux, though, so they may have to be moved.

dc86f3229c X86: Fix a comment and adjust the stack base address.
The stack base on my development machine starts one page below where it needs to. I don't know why it does, but I've duplicated it in m5.

e996ff7497 X86: Fix up auxiliary vectors.
The type constants should go into an architecture independent spot since they are universal to all Linux elf binaries. The right value for some of the vectors needs to be determined. Also, x86 does not store argc or argv_array_base in registers like some other architectures.

d1e533a1e2 X86: Fix argument register indexing.
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg.

05c86ec0d7 Get X86 to load an elf and start a process for it.
src/arch/x86/SConscript:
    Add in process source files.
src/arch/x86/isa_traits.hh:
    Replace magic constant numbers with the x86 register names.
src/arch/x86/miscregfile.cc:
    Make clear the miscreg file succeed. There aren't any misc regs, so clearing them is very easy.
src/arch/x86/process.hh:
    An X86 process class.
src/base/loader/elf_object.cc:
    Add in code to recognize x86 as an architecture.
src/base/traceflags.py:
    Add an x86 traceflag
src/sim/process.cc:
    Add in code to create an x86 process.
src/arch/x86/intregs.hh:
    A file which declares names for the integer register indices.
src/arch/x86/linux/linux.cc:
src/arch/x86/linux/linux.hh:
    A very simple translation of SPARC's linux.cc and linux.hh. It's probably not correct for x86, but it might not be correct for SPARC either.
src/arch/x86/linux/process.cc:
src/arch/x86/linux/process.hh:
    An x86 linux process. The syscall table is split out into it's own file.
src/arch/x86/linux/syscalls.cc:
    The x86 Linux syscall table and the uname function.
src/arch/x86/process.cc:
    The x86 process base class.
tests/test-progs/hello/bin/x86/linux/hello:
    An x86 hello world test binary.
