Thomas Richter d660c8d814 s390/cpum_cf: Deny all sampling events by counter PMU 
[ Upstream commit ce97123324 ]

Deny all sampling event by the CPUMF counter facility device driver
and return -ENOENT. This return value is used to try other PMUs.
Up to now events for type PERF_TYPE_HARDWARE were not tested for
sampling and returned later on -EOPNOTSUPP. This ends the search
for alternative PMUs. Change that behavior and try other PMUs
instead.

Fixes: 613a41b0d1 ("s390/cpum_cf: Reject request for sampling in event initialization")

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.
