Merge tag 'x86_sgx_for_6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull Intel software guard extension (SGX) updates from Dave Hansen:
 "A couple of x86/sgx changes.

  The first one is a no-brainer to use the (simple) SHA-256 library.

  For the second one, some folks doing testing noticed that SGX systems
  under memory pressure were inducing fatal machine checks at pretty
  unnerving rates, despite the SGX code having _some_ awareness of
  memory poison.

  It turns out that the SGX reclaim path was not checking for poison
  _and_ it always accesses memory to copy it around. Make sure that
  poisoned pages are not reclaimed"

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 reStructuredText 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.
