Subject: [PATCH] media: cedrus: Don't kernel map most buffers
Except VP8 probability coefficients buffer, all other buffers are never
accessed by CPU. That allows us to mark them with DMA_ATTR_NO_KERNEL_MAPPING
flag. This helps with decoding big (like 4k) videos on 32-bit ARM
platforms where default vmalloc size is relatively small - 240 MiB.
Since auxiliary buffer are not yet efficiently allocated, this can be
easily exceeded. Even if allocation is optimized, 4k videos will still
often exceed this limit.
