Will Deacon bd62f1fe73 arm64: debug: Don't propagate UNKNOWN FAR into si_code for debug signals ... commit b9a4b9d084 upstream. FAR_EL1 is UNKNOWN for all debug exceptions other than those caused by taking a hardware watchpoint. Unfortunately, if a debug handler returns a non-zero value, then we will propagate the UNKNOWN FAR value to userspace via the si_addr field of the SIGTRAP siginfo_t. Instead, let's set si_addr to take on the PC of the faulting instruction, which we have available in the current pt_regs.
