Linus Torvalds d41e5839d8 Merge tag 'cxl-for-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
 "The most significant changes in this pull request is the series that
  introduces ACQUIRE() and ACQUIRE_ERR() macros to replace conditional
  locking and ease the pain points of scoped_cond_guard().

  The series also includes follow on changes that refactor the CXL
  sub-system to utilize the new macros.

  Detail summary:

   - Add documentation template for CXL conventions to document CXL
     platform quirks

   - Replace mutex_lock_io() with mutex_lock() for mailbox

   - Add location limit for fake CFMWS range for cxl_test, ARM platform
     enabling

   - CXL documentation typo and clarity fixes

   - Use correct format specifier for function cxl_set_ecs_threshold()

   - Make cxl_bus_type constant

   - Introduce new helper cxl_resource_contains_addr() to check address
     availability

   - Fix wrong DPA checking for PPR operation

   - Remove core/acpi.c and CXL core dependency on ACPI

   - Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks

   - Add CXL updates utilizing ACQUIRE() macro to remove gotos and
     improve readability

   - Add return for the dummy version of cxl_decoder_detach() without
     CONFIG_CXL_REGION

   - CXL events updates for spec r3.2

   - Fix return of __cxl_decoder_detach() error path

   - CXL debugfs documentation fix"

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.
