commita019b36123upstream. On s390 FORCE_MAX_ZONEORDER is 9 instead of 11, thus a larger kzalloc() allocation as done for the firmware tracer will always fail. Looking at mlx5_fw_tracer_save_trace(), it is actually the driver itself that copies the debug data into the trace array and there is no need for the allocation to be contiguous in physical memory. We can therefor use kvzalloc() instead of kzalloc() and get rid of the large contiguous allcoation.

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.
