Subject: [PATCH 0/2] Misc fixes for Xen grant DMA-mapping layer

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@...m.com>

Hello all.

These are several fixes I collected when playing with virtio-net device
using Xen grant mappings.

Tested with both virtio-blk and virtio-net devices.

Oleksandr Tyshchenko (2):
  xen/virtio: Fix n_pages calculation in xen_grant_dma_map(unmap)_page()
  xen/virtio: Fix potential deadlock when accessing
    xen_grant_dma_devices
