Add missing @ tags for some rpmsg_eptdev structure parameters.
This fixes warning messages on build:
drivers/rpmsg/rpmsg_char.c:75: warning: Function parameter or struct member
'remote_flow_restricted' not described in 'rpmsg_eptdev'

The new request is called `IOCTL_VM_SOCKETS_GET_LOCAL_CIDS`. And the old
one, `IOCTL_VM_SOCKETS_GET_LOCAL_CID` is retained.
For the transport that supports multi-devices:
* `IOCTL_VM_SOCKETS_GET_LOCAL_CID` returns "-1";
* `IOCTL_VM_SOCKETS_GET_LOCAL_CIDS` returns a vector of CIDS. The usage is
sh
Adds a new argument, named "src_cid", to let them know which `virtio_vsock`
to be selected.

The maximum number of devices is limited by `MAX_VSOCK_NUM`.
Extends `vsock_transport` struct with 4 methods to support multi-devices:
* `get_virtio_vsock()`: It receives a CID, and returns a struct of virtio
vsock. This method is designed to select a vsock device by its CID.
* `get_default_cid
The "order" field determines the location of the device in the linked list,
the device with CID 4, having a smallest order, is in the first place, and
so forth.
Rules:
* It doesn’t have to be continuous;
* It cannot exist conflicts;
* It is optional for the mode of a single device, but is require
# Motivition
Vsock is a lightweight and widely used data exchange mechanism between host
and guest. Kata Containers, a secure container runtime, leverages the
capability to exchange control data between the shim and the kata-agent.
The Linux kernel only supports one vsock device for virtio-vsock

The reader code in rb_get_reader_page() swaps a new reader page into the
ring buffer by doing cmpxchg on old->list.prev->next to point it to the
new page. Following that, if the operation is successful,
old->list.next->prev gets updated too. This means the underlying
doubly-linked list is temporari
Adjust the following code documentation:
* Kernel-doc comments for ring_buffer_read_prepare() and
ring_buffer_read_finish() mention that recording to the ring buffer is
disabled when the read is active. Remove mention of this restriction
because it was already lifted in commit 1039221cc278 (
Fix a race between a reader swapping a new reader page into the
ring-buffer from rb_get_reader_page() and the rb_check_pages() check
invoked at the end of the resize operation in ring_buffer_resize().
Note that a similar problem with rb_check_pages() being executed with
concurrent readers looks to
Two enclave threads may try to add and remove the same enclave page
simultaneously (e.g., if the SGX runtime supports both lazy allocation
and MADV_DONTNEED semantics). Consider some enclave page added to the
enclave. User space decides to temporarily remove this page (e.g.,
emulating the MADV_DONT

SGX runtimes such as Gramine may implement EDMM-based lazy allocation of
enclave pages and may support MADV_DONTNEED semantics [1]. The former
implies #PF-based page allocation, and the latter implies the usage of
SGX_IOC_ENCLAVE_REMOVE_PAGES ioctl.
