Thomas Gleixner 7623f37e41 x86/cpu_entry_area: Provide exception stack accessor
Store a pointer to the per cpu entry area exception stack mappings to allow
fast retrieval.

Required for converting various places from using the shadow IST array to
directly doing address calculations on the actual mapping address.

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.
