LF-228 drivers: pci: dwc: pci-imx6: handle the abort from user-space The driver install one hook to handle the external abort, but issue is that if the abort introduced from user space code, the following code unsigned long instr = *(unsigned long *)pc; which will created another data-abort(page domain fault) if CONFIG_CPU_SW_DOMAIN_PAN. The patch does not intent to use copy_from_user and then do the hack due to the security consideration. In fact, we can just return and report the external abort to user-space.
