From 33f21860b766701f92c01094dcfc5390974d4020 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Mon, 10 Jul 2023 11:49:29 +0200 Subject: [PATCH] hw/virtio/vhost-vdpa: Use target-agnostic qemu_target_page_mask() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Similarly to commit e414ed2c47 ("virtio-iommu: Use target-agnostic qemu_target_page_mask"), Replace the target-specific TARGET_PAGE_SIZE and TARGET_PAGE_MASK definitions by a call to the runtime qemu_target_page_size() helper which is target agnostic.
