We need to add a new thread flag, TIF_EMULATE_STACK_STORE,
for emulating stack store operation while exiting exception.

We can't emulate stwu since that may corrupt current exception stack.
So we will have to do real store operation in the exception return code.
Firstly we'll allocate a trampoline exception frame below the kprobed
function stack and copy the current exception frame to the trampoline.
Then we can
We don't do the real store operation for kprobing 'stwu Rx,(y)R1'
since this may corrupt the exception frame, now we will do this
operation safely in exception return code after migrate current
exception frame below the kprobed function stack.
So we only update gpr[1] here and trigger a thread

The EEH core is talking with the PCI device driver to determine the
