Pull x86 sgx updates from Dave Hansen:
"The biggest deal in this series is support for a new hardware feature
that allows enclaves to detect and mitigate single-stepping attacks.
There's also a minor performance tweak and a little piece of the
kmap_atomic() -> kmap_local() transition.
Summary:
- Introduce a new SGX feature (Asynchrounous Exit Notification) for
bare-metal enclaves and KVM guests to mitigate single-step attacks
- Increase batching to speed up enclave release
- Replace kmap/kunmap_atomic() calls"

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.
