arm64: KVM: use 'int' instead of 'u32' for variable 'target' in kvm_host.h.
'target' will be set to '-1' in kvm_arch_vcpu_init(), and it need check 'target' whether less than zero or not in kvm_vcpu_initialized(). So need define target as 'int' instead of 'u32', just like ARM has done. The related warning: arch/arm64/kvm/../../../arch/arm/kvm/arm.c:497:2: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] Signed-off-by: Chen Gang <gang.chen@asianux.com> [Marc: reformated the Subject line to fit the series] Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
