From ec066de1a567169c4737a5933218c329cedf52bd Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Mon, 16 Sep 2019 09:51:33 +0000 Subject: arm: xen: mm: use __GPF_DMA32 for arm64 arm64 shares some code under arch/arm/xen, including mm.c. However ZONE_DMA is removed by commit ad67f5a6545("arm64: replace ZONE_DMA with ZONE_DMA32"). So add a check if CONFIG_ZONE_DMA32 is enabled use __GFP_DMA32.
