From 175add1981e53d22caba8f42d5f924a4de507b6c Mon Sep 17 00:00:00 2001 From: John Keller Date: Mon, 24 Nov 2008 16:47:17 -0600 Subject: [IA64] SN specific version of dma_get_required_mask() Create a platform specific version of dma_get_required_mask() for ia64 SN Altix. All SN Altix platforms support 64 bit DMA addressing regardless of the size of system memory. Create an ia64 machvec for dma_get_required_mask, with the SN version unconditionally returning DMA_64BIT_MASK.
