Linus Torvalds 1f1c153e40 powerpc updates for 5.18
- Enforce kernel RO, and implement STRICT_MODULE_RWX for 603.
 
  - Add support for livepatch to 32-bit.
 
  - Implement CONFIG_DYNAMIC_FTRACE_WITH_ARGS.
 
  - Merge vdso64 and vdso32 into a single directory.
 
  - Fix build errors with newer binutils.
 
  - Add support for UADDR64 relocations, which are emitted by some toolchains. This allows
    powerpc to build with the latest lld.
 
  - Fix (another) potential userspace r13 corruption in transactional memory handling.
 
  - Cleanups of function descriptor handling & related fixes to LKDTM.

Pull powerpc updates from Michael Ellerman:
 "Livepatch support for 32-bit is probably the standout new feature,
  otherwise mostly just lots of bits and pieces all over the board.

  There's a series of commits cleaning up function descriptor handling,
  which touches a few other arches as well as LKDTM. It has acks from
  Arnd, Kees and Helge.

  Summary:

   - Enforce kernel RO, and implement STRICT_MODULE_RWX for 603.

   - Add support for livepatch to 32-bit.

   - Implement CONFIG_DYNAMIC_FTRACE_WITH_ARGS.

   - Merge vdso64 and vdso32 into a single directory.

   - Fix build errors with newer binutils.

   - Add support for UADDR64 relocations, which are emitted by some
     toolchains. This allows powerpc to build with the latest lld.

   - Fix (another) potential userspace r13 corruption in transactional
     memory handling.

   - Cleanups of function descriptor handling & related fixes to LKDTM.

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.
