As reported by "kbuild test robot" there were some errors and warnings on attempt to build kernel with "make ARCH=powerpc allmodconfig". And this patch addresses both errors and warnings. Below is a list of introduced changes: 1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC. 2. Use DMA address instead of "skb->data" as a pointer to data buffer. This fixed warnings on pointer to int conversion on 64-bit systems. 3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in the same way they're re-allocated during operation (receiving packets). So once again DMA address could be used instead of "skb->data". 4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.
