In xen/arch/x86/hvm/hvm.c:

#define HYPERCALL(x) \
[ __HYPERVISOR_ ## x ] = (hvm_hypercall_t *) do_ ## x

#if defined(__i386__)

static hvm_hypercall_t *hvm_hypercall32_table[NR_hypercalls] = {
    HYPERCALL(memory_op),
    [ __HYPERVISOR_grant_table_op ] = (hvm_hypercall_t *)hvm_grant_table_op,
    HYPERCALL(xen_version),
    HYPERCALL(grant_table_op),
    HYPERCALL(event_channel_op),
    HYPERCALL(sched_op),
    HYPERCALL(hvm_op)
};

#else /* defined(__x86_64__) */

-------------------

For the index __HYPERVISOR_grant_table_op, there are 2 assignments -- do_grant_table_op(), and hvm_grant_table_op() here???

What's the purpose by doing so?
