From: Alex Bennée Date: Tue, 1 Jul 2014 15:53:13 +0000 (+0100) Subject: arm64: KVM: export demux regids as KVM_REG_ARM64 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=efd48ceacea78e4d4656aa0a6bf4c5b92ed22130;p=linux-beck.git arm64: KVM: export demux regids as KVM_REG_ARM64 I suspect this is a -ECUTPASTE fault from the initial implementation. If we don't declare the register ID to be KVM_REG_ARM64 the KVM_GET_ONE_REG implementation kvm_arm_get_reg() returns -EINVAL and hilarity ensues. The kvm/api.txt document describes all arm64 registers as starting with 0x60xx... (i.e KVM_REG_ARM64).
