The patch titled
dma-mapping: pci: convert pci_set_dma_mask to call dma_set_mask
has been removed from the -mm tree. Its filename was
dma-mapping-pci-convert-pci_set_dma_mask-to-call-dma_set_mask.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: dma-mapping: pci: convert pci_set_dma_mask to call dma_set_mask
From: FUJITA Tomonori <fujita.tomonori@xxxxxxxxxxxxx>
This changes pci_set_dma_mask to call the generic DMA API, dma_set_mask.
pci_set_dma_mask (in drivers/pci/pci.c) does the same things that
dma_set_mask does on all the architectures that use pci_set_dma_mask;
calls dma_supprted and sets dev->dma_mask. So we safely change
pci_set_dma_mask to simply call dma_set_mask.
