This module allows m5ops to be executed in Lua programs.
To compile it (in util/m5):
The following command generates Lua moduel, gem5OpLua.so.
make -f Makefile.<arch> gem5OpLua.so
To use it:
First, put gem5OpLua.so in Lua library search path.
Then, import the module and execute the m5op function.
Example usage, creating a checkpoint.
m5 = require("gem5OpLua")
m5.do_checkpoint(0, 0)

The header file m5ops.h contains a list of constants that should be
shared between the simulator and utilities. Move this header file to a
new top-level directory for shared files and rename constants to make
them suitable for inclusion in the main simulator.
The structure of the shared include directory is as follows:
include/gem5: Files that can be included from C code.
include/gem5/asm: Files that can be included from assembly code.
asm/generic/: Files that aren't guest ISA specific
asm/${isa}/: Files that are guest ISA specific

In order to support m5ops in virtualized environments, we need to use
a memory mapped interface. This changeset adds support for that by
reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR
interface for m5ops. The mapping is done in the
X86ISA::TLB::finalizePhysical() which means that it just works for all
of the CPU models, including virtualized ones.
