I would like to kindly ask you for removal of this patch. This patch should be reverted from all stable kernels up to 5.1, because perf counters were not broken on those kernels, and this patch won't work on the ath79 legacy IRQ code anyway, it needs new irqchip driver which was enabled on ath79 with commit 51fa4f8912c0 ("MIPS: ath79: drop legacy IRQ code"). Thanks! Cheers, Petr
