From 936577c61d0c10b8929608a92c98d839b22053bc Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 22 Feb 2009 10:27:49 -0800 Subject: x86: Add IRQF_TIMER to legacy x86 timer interrupt descriptors Right now nobody cares, but the suspend/resume code will eventually want to suspend device interrupts without suspending the timer, and will depend on this flag to know. The modern x86 timer infrastructure uses the local APIC timers and never shows up as a device interrupt at all, so it isn't affected and doesn't need any of this. Cc: Rafael J.
