I am currently using IPR_ICM register to check if an instruction is from an
application or from the OS so that I won't Inject Fault on the OS.
So in my case lets say in the fetch_impl.hh file I have added after the
fetching of the original instruction the following code
//Instruction fetch
if (cpu->readMiscReg(AlphaISA::IPR_ICM, tid) !=
AlphaISA::mode_kernel) {
//Fault Injection
}
