This patchset adds API and one user for a "weak" dma_set_mask(). Weak means that it will fallback to smaller masks in case the DMA subsystem rejects a big mask. Currently such rejection may happen if the driver requests a 64bit mask on a VIA machine, for example. dma_set_mask_weak() will fallback to 32bit, in that case, and tell the caller about it by modifying the passed mask. I'm not sure how we should merge this patchset. I'd suggest we merge it all through John Linville for 2.6.27, as the only current user of the API is the b43 wireless driver. We could split it and push the nonwireless parts to somebody else's tree, but I'm not sure it's worth the trouble. -- Greetings Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
