Subject: [PATCH v7 06/15] KVM: s390: remove kvm_s390_ from gisa static inline functions
Date:   Thu, 31 Jan 2019 09:52:37 +0100
In-Reply-To: <20190131085247.13826-1-mimu@linux.ibm.com>
References: <20190131085247.13826-1-mimu@linux.ibm.com>
Message-Id: <20190131085247.13826-7-mimu@linux.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This will shorten the length of code lines. All GISA related
static inline functions are local to interrupt.c.
