The linux-next integration testing tree

And extract sgx_set_attribute() out of sgx_ioc_enclave_provision() and export it as symbol for KVM to use. The provisioning key is sensitive. The SGX driver only allows to create an enclave which can access the provisioning key when the enclave creator has permission to open /dev/sgx_provision. It should apply to a VM as well, as the provisioning key is platform-specific, thus an unrestricted VM can also potentially compromise the provisioning key. Move the provisioning device creation out of sgx_drv_init() to sgx_init() as a preparation for adding SGX virtualization support, so that even if the SGX driver is not enabled due to flexible launch control not being available, SGX virtualization can still be enabled, and use it to restrict a VM's capability of being able to access the provisioning key.

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.
