Linus Torvalds 362f533a2a cxl for 5.17
- Rework ACPI sub-table infrastructure to optionally be used outside of
   __init scenarios and use it for CEDT.CFMWS sub-table parsing.
 - Add support for extending num_possible_nodes by the potential hotplug
   CXL memory ranges
 - Extend tools/testing/cxl with mock memory device health information
 - Fix a module-reload workqueue race
 - Fix excessive stack-frame usage
 - Rename the driver context data structure from "cxl_mem" since that
   name collides with a proposed driver name
 - Use EXPORT_SYMBOL_NS_GPL instead of -DDEFAULT_SYMBOL_NAMESPACE at
   build time

Merge tag 'cxl-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The highlight is initial support for CXL memory hotplug. The static
  NUMA node (ACPI SRAT Physical Address to Proximity Domain) information
  known to platform firmware is extended to support the potential
  performance-class / memory-target nodes dynamically created from
  available CXL memory device capacity.

  New unit test infrastructure is added for validating health
  information payloads.

  Fixes to module reload stress and stack usage from exposure in -next
  are included. A symbol rename and some other miscellaneous fixups are
  included as well.

  Summary:

   - Rework ACPI sub-table infrastructure to optionally be used outside
     of __init scenarios and use it for CEDT.CFMWS sub-table parsing.

   - Add support for extending num_possible_nodes by the potential
     hotplug CXL memory ranges

   - Extend tools/testing/cxl with mock memory device health information

   - Fix a module-reload workqueue race

   - Fix excessive stack-frame usage

   - Rename the driver context data structure from "cxl_mem" since that
     name collides with a proposed driver name

   - Use EXPORT_SYMBOL_NS_GPL instead of -DDEFAULT_SYMBOL_NAMESPACE at
     build time"

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.
