That means your code in your patch won't work= if this kernel option is enabled. +#ifndef CONFIG_ARCH_DMA_ADDR_T_64BIT + /* Check if DMA address overflowed */ + if (min(addr, addr + size - 1) < + __phys_to_dma(dev, (phys_addr_t)(min_low_pfn << PAGE_SHIFT))) + return false; +#endif I will delete the lines with ifndef and endif and will try it again. Cheers, Christian --=20 You are receiving this mail because: You are watching the assignee of the bug.=
