KVM: nVMX: Properly pad 'struct kvm_vmx_nested_state_hdr'
Eliminate the probably unwanted hole in 'struct kvm_vmx_nested_state_hdr':
Pre-patch:
struct kvm_vmx_nested_state_hdr {
__u64 vmxon_pa; /* 0 8 */
__u64 vmcs12_pa; /* 8 8 */
struct {
__u16 flags; /* 16 2 */
} smm; /* 16 2 */
/* XXX 2 bytes hole, try to pack */
__u32 flags; /* 20 4 */
__u64 preemption_timer_deadline; /* 24 8 */
};
Post-patch:
struct kvm_vmx_nested_state_hdr {
__u64 vmxon_pa; /* 0 8 */
__u64 vmcs12_pa; /* 8 8 */
struct {
__u16 flags; /* 16 2 */
} smm; /* 16 2 */
__u16 pad; /* 18 2 */
__u32 flags; /* 20 4 */
__u64 preemption_timer_deadline; /* 24 8 */
};
