Andra Paraschiv 1df624892c nitro_enclaves: Define enclave info for internal bookkeeping
The Nitro Enclaves driver keeps an internal info per each enclave.

This is needed to be able to manage enclave resources state, enclave
notifications and have a reference of the PCI device that handles
command requests for enclave lifetime management.

Changelog

v9 -> v10

* Update commit message to include the changelog before the SoB tag(s).

v8 -> v9

* Add data structure to keep references to both Nitro Enclaves misc and
  PCI devices.

v7 -> v8

* No changes.

v6 -> v7

* Update the naming and add more comments to make more clear the logic
  of handling full CPU cores and dedicating them to the enclave.

v5 -> v6

* Update documentation to kernel-doc format.
* Include in the enclave memory region data structure the user space
  address and size for duplicate user space memory regions checks.

v4 -> v5

* Include enclave cores field in the enclave metadata.
* Update the vCPU ids data structure to be a cpumask instead of a list.

v3 -> v4

* Add NUMA node field for an enclave metadata as the enclave memory and
  CPUs need to be from the same NUMA node.

v2 -> v3

* Remove the GPL additional wording as SPDX-License-Identifier is
  already in place.

v1 -> v2

* Add enclave memory regions and vcpus count for enclave bookkeeping.
* Update ne_state comments to reflect NE_START_ENCLAVE ioctl naming
  update.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
