[PATCH v2 7/8] virtio/s390: use DMA memory for ccw I/O and classic notifiers
From: Halil Pasic <pasic at linux.ibm.com> Before virtio-ccw could get away with not using DMA API for the pieces of memory it does ccw I/O with. With protected virtualization this has to change, since the hypervisor needs to read and sometimes also write these pieces of memory. The hypervisor is supposed to poke the classic notifiers, if these are used, out of band with regards to ccw
