Hmm, we did apply your series on top of kvarm/next, judging from the function
code below, I can't see the 'its' declaration.
static int vgic_its_has_attr(struct kvm_device *dev,
struct kvm_device_attr *attr)
{
switch (attr->group) {
case KVM_DEV_ARM_VGIC_GRP_ADDR:
switch (attr->attr) {
case KVM_VGIC_ITS_ADDR_TYPE:
return 0;
}
break;
case KVM_DEV_ARM_VGIC_GRP_CTRL:
switch (attr->attr) {
case KVM_DEV_ARM_VGIC_CTRL_INIT:
return 0;
}
break;
case KVM_DEV_ARM_VGIC_GRP_ITS_REGS: {
u64 __user *uaddr = (u64 __user *)(long)attr->addr;
u64 reg;
if (get_user(reg, uaddr))
return -EFAULT;
return vgic_its_attr_regs_access(dev, attr, ®, true);
}
case KVM_DEV_ARM_VGIC_GRP_ITS_TABLES:
if (attr->attr)
return -EINVAL;
return vgic_its_table_restore(its);
}
return -ENXIO;
}
