Subject: [PATCH] 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]
