From f481973d5efdb63b7c6ca6b0ecd2b8462556a461 Mon Sep 17 00:00:00 2001 From: Mahesh Rajashekhara Date: Wed, 5 Apr 2017 16:14:16 +0530 Subject: scsi: aacraid: pci_alloc_consistent() failures on ARM64 There were pci_alloc_consistent() failures on ARM64 platform. Use dma_alloc_coherent() with GFP_KERNEL flag DMA memory allocations.
