This commit modifies the mask of the mrs_hook declared in arch/arm64/kernel/cpufeatures.c which emulates only feature register access. This is necessary because this hook's mask was too large and thus masking any mrs instruction, even if not related to the emulated registers which made the pmu emulation inefficient.

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.
