From 4965a68780c5ccad4082434e264953fba0f9bcf6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 3 Apr 2018 16:26:52 +0200 Subject: arch: define the ARCH_DMA_ADDR_T_64BIT config symbol in lib/Kconfig Define this symbol if the architecture either uses 64-bit pointers or the PHYS_ADDR_T_64BIT is set. This covers 95% of the old arch magic. We only need an additional select for Xen on ARM (why anyway?), and we now always set ARCH_DMA_ADDR_T_64BIT on mips boards with 64-bit physical addressing instead of only doing it when highmem is set.
