ARM: hw_breakpoint: fix ordering of debug register reset sequence The debug register reset sequence for v7 and v7.1 is congruent with tap-dancing through a minefield. Rather than wait until we've blown ourselves to pieces, this patch instead checks the debug_err_mask after each potentially faulting operation. We also move the enabling of monitor_mode to the end of the sequence in order to prevent spurious debug events generated by UNKNOWN register values.
