+Subject: [PATCH] arm: export dma_set_coherent_mask
+
+While a regression was fixed with commit 710224fa2750cf (arm: fix
+"arm: fix pci_set_consistent_dma_mask for dmabounce devices"), a
+new one was introduced as dma_set_coherent_mask wasn't exported
+for modules. This patch takes care for this issue.
