Sergei Shtylyov 1debdc8f9e sh_eth: unmap DMA buffers when freeing rings ... The DMA API debugging (when enabled) causes: WARNING: CPU: 0 PID: 1445 at lib/dma-debug.c:519 add_dma_entry+0xe0/0x12c DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d to be printed after repeated initialization of the Ether device, e.g. suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are never unmapped. Resolve this problem by unmapping the buffers when freeing the descriptor rings; in order to do it right, we'd have to add an extra parameter to sh_eth_txfree() (we rename this function to sh_eth_tx_free(), while at it).
