On IA64, new sparse's warnings where issued after fixing some __rcu annotations in kernel/bpf/. These new warnings are false positives and appear on IA64 because on this architecture, the macros for cmpxchg() and xchg() make casts that ignore sparse annotations. This patch contains the minimal patch to fix this issue: adding a missing cast and some missing '__force'.

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.
