1. Add shadow stack support to x32 signal. 2. Use the 64-bit map_shadow_stack syscall for x32. 3. Set up shadow stack for x32. Tested with shadow stack enabled x32 glibc on Intel Tiger Lake: I configured x32 glibc with --enable-cet, build glibc and run all glibc tests with shadow stack enabled. There are no regressions. I verified that shadow stack is enabled via /proc/pid/status. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Signed-off-by: Ingo Molnar <mingo@kernel.org> Tested-by: H.J.

README
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.
