In 9422de3 "powerpc: Hardware breakpoints rewrite to handle non DABR breakpoint

-			(dar - bp->attr.bp_addr < bp->attr.bp_len));
+	if (!((bp->attr.bp_addr <= dar) &&

Unfortunately this is bogus as it never clears extraneous IRQ if it's already
set.

This correctly clears extraneous IRQ before possibly setting it.
