X-Received-From: 192.55.52.115 Subject: [Qemu-devel] [PATCH v3 06/10] hw/s390x: Replace global smp variables with machine smp properties X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Peter Maydell , Eduardo Habkost , qemu-devel@nongnu.org, "Dr . David Alan Gilbert" , Alistair Francis , Igor Mammedov Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" The global smp variables in s390x are replaced with smp machine properties. A local variable of the same name would be introduced in the declaration phase if it's used widely in the context OR replace it on the spot if it's only used once. No semantic changes.
