Linus Torvalds bf953917be Various hardening fixes and cleanups for 5.16-rc1 
Hi Linus,
 
 Please, pull the following hardening fixes and cleanups that I've
 been collecting during the last development cycle. All of them have
 been baking in linux-next.
 
 Fix -Wcast-function-type error:
 
 - firewire: Remove function callback casts (Oscar Carter)
 
 Fix application of sizeof operator:
 
 - firmware/psci: fix application of sizeof to pointer (jing yangyang)
 
 Replace open coded instances with size_t saturating arithmetic helpers:
 
 - assoc_array: Avoid open coded arithmetic in allocator arguments (Len Baker)
 - writeback: prefer struct_size over open coded arithmetic (Len Baker)
 - aio: Prefer struct_size over open coded arithmetic (Len Baker)
 - dmaengine: pxa_dma: Prefer struct_size over open coded arithmetic (Len Baker)
 
 Flexible array transformation:
 
 - KVM: PPC: Replace zero-length array with flexible array member (Len Baker)
 
 Use 2-factor argument multiplication form:
 
 - nouveau/svm: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)
 - xfs: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)
 
 Thanks

 Gustavo

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.
