s390 is the only architecture that is using own bust_spinlocks() variant, while other arch-s seem to be OK with the common implementation. Heiko Carstens [1] said he would prefer s390 to use the common bust_spinlocks() as well: I did some code archaeology and this function is unchanged since ~17 years. When it was introduced it was close to identical to the x86 variant. All other architectures use the common code variant in the meantime. So if we change this I'd prefer that we switch s390 to the common code variant as well. Right now I can't see a reason for not doing that This patch removes s390 bust_spinlocks() and drops the weak attribute from the common bust_spinlocks() version.

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.
