Subject: [PATCH 2/4] ACPI: Make ACPI interrupt threaded
Date: Mon, 26 Dec 2011 22:34:45 -0800	[thread overview]
Message-ID: <1324967687-10559-3-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1324967687-10559-1-git-send-email-andi@firstfloor.org>

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.
