For this case, do you want me to resend this patch in next merge
window? Or you have picked up this patch but will send PR in next
cycle?
Thanks,

This patch implements arm specific functions regs_set_return_value() and
override_function_with_return() to support function error injection.
In the exception flow, it updates pt_regs::ARM_pc with pt_regs::ARM_lr
so can override the probed function return.

r function is
override_function_with_return() which is to override the probed
function returning and jump to its caller.
