Before setting the memory regions for the enclave, the enclave image needs to be placed in memory. After the memory regions are set, this memory cannot be used anymore by the VM, being carved out. Add ioctl command logic to get the offset in enclave memory where to place the enclave image. Then the user space tooling copies the enclave image in the memory using the given memory offset. Changelog v9 -> v10 * Update commit message to include the changelog before the SoB tag(s). v8 -> v9 * No changes. v7 -> v8 * Add custom error code for incorrect enclave image load info flag. v6 -> v7 * No changes. v5 -> v6 * Check for invalid enclave image load flags. v4 -> v5 * Check for the enclave not being started when invoking this ioctl call. * Remove log on copy_from_user() / copy_to_user() failure. v3 -> v4 * Use dev_err instead of custom NE log pattern. * Set enclave image load offset based on flags. * Update the naming for the ioctl command from metadata to info. v2 -> v3 * No changes. v1 -> v2 * New in v2.

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.
