From 7513cc8a1b741bee6fb39cbb94a9842d37ca3ace Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 26 May 2021 20:36:20 +0100 Subject: arm64: Change the cpuinfo_arm64 member type for some sysregs to u64 The architecture has been updated and the CTR_EL0, CNTFRQ_EL0, DCZID_EL0, MIDR_EL1, REVIDR_EL1 registers are all 64-bit, even if most of them have a RES0 top 32-bit. Change their type to u64 in struct cpuinfo_arm64.
