From 8a53ad675f86ee003482b557da944e070d3c4859 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 8 Sep 2008 18:10:12 +0900 Subject: x86: fix nommu_alloc_coherent allocation with NULL device argument We need to use __GFP_DMA for NULL device argument (fallback_dev) with pci-nommu. It's a hack for ISA (and some old code) so we need to use GFP_DMA.
