commit 0209b5830bea42dd3ce33ab0397231e67ec3b751 upstream. Some of the SBI PMU calls does not pass 64bit arguments correctly and not under RV32 compile time flags. Currently, this doesn't create any incorrect results as RV64 ignores any value in the additional register and qemu doesn't support raw events. Fix those SBI calls in order to set correct values for RV32.

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.
