Documentation: move Documentation/virtual to Documentation/virt
Renaming docs seems to be en vogue at the moment, so fix on of the grossly misnamed directories. We usually never use "virtual" as a shortcut for virtualization in the kernel, but always virt, as seen in the virt/ top-level directory. Fix up the documentation to match that. Fixes: ed16648eb5b8 ("Move kvm, uml, and lguest subdirectories under a common "virtual" directory, I.E:") Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

-VFIO virtual device
-===================
-
-Device types supported:
- KVM_DEV_TYPE_VFIO
-
-Only one VFIO instance may be created per VM. The created device
-tracks VFIO groups in use by the VM and features of those groups
-important to the correctness and acceleration of the VM. As groups
-are enabled and disabled for use by the VM, KVM should be updated
-about their presence. When registered with KVM, a reference to the
-VFIO-group is held by KVM.
-
-Groups:
- KVM_DEV_VFIO_GROUP
-
-KVM_DEV_VFIO_GROUP attributes:
- KVM_DEV_VFIO_GROUP_ADD: Add a VFIO group to VFIO-KVM device tracking
- kvm_device_attr.addr points to an int32_t file descriptor
- for the VFIO group.
- KVM_DEV_VFIO_GROUP_DEL: Remove a VFIO group from VFIO-KVM device tracking
- kvm_device_attr.addr points to an int32_t file descriptor
- for the VFIO group.
- KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE: attaches a guest visible TCE table
- allocated by sPAPR KVM.
- kvm_device_attr.addr points to a struct:
-
- struct kvm_vfio_spapr_tce {
- __s32 groupfd;
- __s32 tablefd;
- };
-
- where
- @groupfd is a file descriptor for a VFIO group;
- @tablefd is a file descriptor for a TCE table allocated via
- KVM_CREATE_SPAPR_TCE.
