In 9422de3 "powerpc: Hardware breakpoints rewrite to handle non DABR breakpoint
registers" we changed the way we mark extraneous irqs with this:
- info->extraneous_interrupt = !((bp->attr.bp_addr <= dar) &&
- (dar - bp->attr.bp_addr < bp->attr.bp_len));
+ if (!((bp->attr.bp_addr <= dar) &&
+ (dar - bp->attr.bp_addr < bp->attr.bp_len)))
+ info->type |= HW_BRK_TYPE_EXTRANEOUS_IRQ;
Unfortunately this is bogus as it never clears extraneous IRQ if it's already
set.
This correctly clears extraneous IRQ before possibly setting it.
