3.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Brian W Hart <hartb@xxxxxxxxxxxxxxxxxx> commit a32305bf90a2ae0e6a9a93370c7616565f75e15a upstream. powerpc defines various machine-specific routines for handling pci_set_dma_mask(). The routines for machine "PowerNV" may neglect to set dev->dma_mask. This could confuse anyone (e.g. drivers) that consult dev->dma_mask to find the current mask. Set the dma_mask in the PowerNV leaf routine. Signed-off-by: Brian W.
