Intel TSX suspend load tracking instructions aim to give a way to choose which memory accesses do not need to be tracked in the TSX read set. Add TSX suspend load tracking CPUID feature flag TSXLDTRK for enumeration. A processor supports Intel TSX suspend load address tracking if CPUID.0x07.0x0:EDX[16] is present. Two instructions XSUSLDTRK, XRESLDTRK are available when this feature is present. The CPU feature flag is shown as "tsxldtrk" in /proc/cpuinfo.

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.
