Subject: [PATCH] arm: xen: mm: use __GPF_DMA32 for arm64
Date: Tue, 9 Jul 2019 08:22:30 +0000 [thread overview]
Message-ID: <20190709083729.11135-1-peng.fan@nxp.com> (raw)
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 to ARM64, need use __GFP_DMA32.
