On some archs, like tile, the PAGE_SIZE is not 4K. In the case of tile arch, it can be either 16KB or 64KB. Due to that, a warning is produced: drivers/media/pci/saa7134/saa7134.h:678:43: warning: large integer implicitly truncated to unsigned type [-Woverflow] This is actually an error, as it will write trach to the DMA size registers. The logic at saa7134-ts already does the right thing: saa_writeb(SAA7134_TS_DMA0, ((dev->ts.nr_packets-1)&0xff)); saa_writeb(SAA7134_TS_DMA1, (((dev->ts.nr_packets-1)>>8)&0xff)); /* TSNOPIT=0, TSCOLAP=0 */ saa_writeb(SAA7134_TS_DMA2, ((((dev->ts.nr_packets-1)>>16)&0x3f) | 0x00)); So, fix the driver to take larger page sizes into account.
