Sandeepa Prabhu fcfd708b8c arm64: Add kernel return probes support (kretprobes) 
The pre-handler of this special 'trampoline' kprobe executes the return
probe handler functions and restores original return address in ELR_EL1.
This way the saved pt_regs still hold the original register context to be
carried back to the probed kernel function.
