Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported.

This is an attempt to fix the issue that some disks' sysfs attributes are not ready at the time its KOBJ_ADD event is sent. The symptom is during device hotplug, udev may fail to find certain attributes, such as serial or wwn, of the disk. As a result the /dev/disk/by-id entries are not created. The cause is device_add_disk emits the uevent before returning, and the callers have to create
