From e3e02ded3bc4c6b37b1d2669714abdb12f0e2868 Mon Sep 17 00:00:00 2001

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]
