From 6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 6 Feb 2012 08:17:09 -0800 Subject: [PATCH] ACPI: Make ACPI interrupt threaded Some ACPI interrupt actions may need to wait, and it's easiest to have a thread context for this. So turn the ACPI interrupt into a threaded interrupt.
