To implement kvm_arch_reset_vcpu(), we simply re-init the VCPU
using kvm_arm_vcpu_init() so that all registers of VCPU are set
to their reset values by in-kernel KVM code.

No big deal, it will have a small conflict but the functionality will
remain in ARM (just renamed to kvm_arm_reset_vcpu and taking an ARMCPU*).
Thanks for the heads up.
