From 927703cc40fb86b10bd7bb5bb0efa8da69fc6db6 Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Mon, 23 Aug 2021 18:06:45 +0200 Subject: [PATCH] target/arm/kvm64: Ensure sve vls map is completely clear MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit bitmap_clear() only clears the given range. While the given range should be sufficient in this case we might as well be 100% sure all bits are zeroed by using bitmap_zero().
