From 8eb6c6e3b9c8bfed3d75536ab142d7694627c2e5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 6 Jun 2006 16:11:35 +0200 Subject: [PATCH] powerpc: node-aware dma allocations Make sure dma_alloc_coherent allocates memory from the local node. This is important on Cell where we avoid going through the slow cpu interconnect. Note: I could only test this patch on Cell, it should be verified on some pseries machine by those that have the hardware.
