kvm: Add support for pseudo-ops on ARM
This changeset adds support for m5 pseudo-ops when running in kvm-mode. Unfortunately, we can't trap the normal gem5 co-processor entry in KVM (it doesn't seem to be possible to trap accesses to non-existing co-processors). We therefore use BZJ instructions to cause a trap from virtualized mode into gem5. The BZJ instruction is becomes a normal branch to the gem5 fallback code when running in simulated mode, which means that this patch does not need to change the ARM ISA-specific code. Note: This requires a patched host kernel.
