From: Chen Baozi <baozich@xxxxxxxxx> There are 3 places to change: * Initialise vMPIDR value in vcpu_initialise() * Find the vCPU from vMPIDR affinity information when accessing GICD registers in vGIC * Find the vCPU from vMPIDR affinity information when booting with vPSCI in vGIC - Also make the code for PSCI 0.1 use MPIDR-like value as the cpuid.
