kvm: remove IA64 ioctls
KVM ia64 is no longer present so new applications shouldn't use them.
The main problem is that they most likely didn't work even before,
because of a conflict in the #defines:
#define KVM_SET_GUEST_DEBUG _IOW(KVMIO, 0x9b, struct kvm_guest_debug)
#define KVM_IA64_VCPU_SET_STACK _IOW(KVMIO, 0x9b, void *)
The argument to KVM_SET_GUEST_DEBUG is:
struct kvm_guest_debug {
__u32 control;
__u32 pad;
struct kvm_guest_debug_arch arch;
};
struct kvm_guest_debug_arch {
};
meaning that sizeof(struct kvm_guest_debug) == sizeof(void *) == 8
and KVM_SET_GUEST_DEBUG == KVM_IA64_VCPU_SET_STACK.
KVM_SET_GUEST_DEBUG is handled in virt/kvm/kvm_main.c before even calling
kvm_arch_vcpu_ioctl (which would have handled KVM_IA64_VCPU_SET_STACK),
so KVM_IA64_VCPU_SET_STACK would just return -EINVAL.
