Commit0499a78369("ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512") changed the handling of cpumasks on ARM 64bit, what resulted in the strange issues and warnings during cpufreq-dt initialization on some big.LITTLE platforms. This was caused by mixing OPPs between big and LITTLE cores, because OPP-sharing information between big and LITTLE cores is computed on cpumask, which in turn was not zeroed on allocation. Fix this by switching to zalloc_cpumask_var() call.

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.
