| Subject: [PATCH] genirq: Introduce IRQF_NODELAY to disable forced threading for an irq |
| |
| commit 73a269a0cfccbb16c4926ec9f8f6414177424596 in tip. |
| |
| Add the IRQF_NODELAY flag and implicitely mark all timer interrupts |
| IRQF_NODELAY by redefining IRQF_TIMER. |
| |
| [PG: bounce NODELAY up one bit since ONESHOT took old value] |
