Pull x86 SGX updates from Dave Hansen:
"A set of x86/sgx changes focused on implementing the "SGX2" features,
plus a minor cleanup:
- SGX2 ISA support which makes enclave memory management much more
dynamic. For instance, enclaves can now change enclave page
permissions on the fly.
- Removal of an unused structure member"

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.
