Upon booting, I occasionally spotted some BUGs triggered by the internal DMA test routine executed upon driver probing. This was detected by SLUB_DEBUG ("Freechain corrupt" or "Redzone overwritten"). Tracking this down located a problem in passing 0 as offset in dma_map_page(). As kmalloc, especially when used with SLUB_DEBUG, may return a non page aligned address. This patch fixes this issue by passing the correct offset in dma_map_page(). Tested on a custom Armada XP board. Signed-off-by:
