Subject: [PATCH v8 05/13] xen/arm: nr_lrs should be uint8_t
Date: Thu, 22 May 2014 13:32:22 +0100	[thread overview]
Message-ID: <1400761950-25035-5-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.02.1405221325140.14596@kaball.uk.xensource.com>

A later patch is going to use uint8_t to keep track of LRs.
Both GICv3 and GICv2 don't need any more than an uint8_t to keep track
of the number of LRs.
