From d4a451d5fc849f9a0a133255ed197b148fc323d0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 3 Apr 2018 16:24:20 +0200 Subject: arch: remove the ARCH_PHYS_ADDR_T_64BIT config symbol Instead select the PHYS_ADDR_T_64BIT for 32-bit architectures that need a 64-bit phys_addr_t type directly.
