Ilkka Koskinen afadf1fad6 arm64/arm: arm_pmuv3: perf: Don't truncate 64-bit registers
[ Upstream commit 403edfa436 ]

The driver used to truncate several 64-bit registers such as PMCEID[n]
registers used to describe whether architectural and microarchitectural
events in range 0x4000-0x401f exist. Due to discarding the bits, the
driver made the events invisible, even if they existed.

Moreover, PMCCFILTR and PMCR registers have additional bits in the upper
32 bits. This patch makes them available although they aren't currently
used. Finally, functions handling PMXEVCNTR and PMXEVTYPER registers are
removed as they not being used at all.

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.
