Subject: [PATCH 12/22] ia64: replace ZONE_DMA with ZONE_DMA32
Date: Wed, 10 Jan 2018 09:09:22 +0100 [thread overview]
Message-ID: <20180110080932.14157-13-hch@lst.de> (raw)
In-Reply-To: <20180110080932.14157-1-hch@lst.de>
ia64 uses ZONE_DMA for allocations below 32-bits. These days we
name the zone for that ZONE_DMA32, which will allow to use the
dma-direct and generic swiotlb code as-is, so rename it.
