From 908b637fe793165b6aecdc875cdca67c4959a1ad Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Mon, 26 Feb 2007 19:52:06 +0000 Subject: Alignment in mv643xx_eth The driver contains this little piece of candy: #if defined(CONFIG_DMA_NONCOHERENT) || defined(CONFIG_NOT_COHERENT_CACHE) #define ETH_DMA_ALIGN L1_CACHE_BYTES #else #define ETH_DMA_ALIGN 8 #endif Any reason why we're not using dma_get_cache_alignment() instead?
