Actually, my patch seems like a good idea to me but it's one of those
things that someone should probably test. Unless someone can test
goldfish on a 32 bit system with 64 bit dma addresses then maybe the
thing to is to write the new function but preserve the current behavior.
static inline void gf_write_dma_addr(dma_addr_t addr, void __iomem *portl,
void __iomem *porth)
{
writel((u32)data, portl);
/*
* This should be CONFIG_ARCH_DMA_ADDR_T_64BIT but someone needs to
* test it.
*/
#ifdef CONFIG_64BIT
writel(data >> 32, porth);
#endif
}
regards,
dan carpenter
