--- Comment #12 from Christian Zigotzky (chzigot...@xenosoft.de) --- Hi Christoph, I have seen that I have activated the kernel config option CONFIG_ARCH_DMA_ADDR_T_64BIT. 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.
