-Subject: [PATCH 11/11] xen/arm: call dma_to_phys on the dma_addr_t parameter
- of dma_cache_maint
-
-Add a struct device* parameter to dma_cache_maint.
-
-Translate the dma_addr_t parameter of dma_cache_maint by calling
-dma_to_phys. Do it for the first page and all the following pages, in
-case of multipage handling.
