Subject: [RFC PATCH 5/8] AMP: smp: Extend number of IPIs
Date: Mon, 18 Jun 2012 13:30:08 +0200	[thread overview]
Message-ID: <1340019011-18642-6-git-send-email-monstr@monstr.eu> (raw)
In-Reply-To: <1340019011-18642-1-git-send-email-monstr@monstr.eu>

GIC supports up to 16 IPIs.

Signed-off-by: Michal Simek <monstr@monstr.eu>

---
Please correct me if this code is also designed for different
interrupt controller which doesn't support 16 IPIs.
