From e2f466e32f56c8b3ee0d1a40cc39e1c779dfd598 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 24 Feb 2017 14:58:41 -0800 Subject: mm: cma_alloc: allow to specify GFP mask Most users of this interface just want to use it with the default GFP_KERNEL flags, but for cases where DMA memory is allocated it may be called from a different context. No functional change yet, just passing through the flag to the underlying alloc_contig_range function.
