[Qemu-devel] [PATCH v3] virtio: fix vring_align() on 64-bit windows

From: Andrew Baumann
Subject: [Qemu-devel] [PATCH v3] virtio: fix vring_align() on 64-bit windows
Date: Fri, 24 Mar 2017 16:19:43 -0700

long is 32-bits on 64-bit windows, which caused the top half of the
address to be truncated; this patch changes it to use the
QEMU_ALIGN_UP macro which does not suffer the same problem
