3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael Neuling <mikey@xxxxxxxxxxx> commit 540e07c67efe42ef6b6be4f1956931e676d58a15 upstream. 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.
