1126 * vmap interface is introduced. Note that on very old 32-bit architectures
1127 * vmalloc space might be limited and result in vmap calls failing.
1133 * The vmap call can fail if there is no vmap support in the exporter, or if
1135 * that the dma-buf layer keeps a reference count for all vmap access and
1136 * calls down into the exporter's vmap function only when no vmapping exists,
1137 * and only unmaps it once. Protection against concurrent vmap/vunmap calls is
1377 * address space. Same restrictions as for vmap and friends apply.
1378 * @dmabuf: [in] buffer to vmap
1395 if (!dmabuf->ops->vmap) {
1409 ptr = dmabuf->ops->vmap(dmabuf);
1427 * dma_buf_vunmap - Unmap a vmap obtained by dma_buf_vmap.
1429 * @vaddr: [in] vmap to vunmap
