Sudeep Holla 7401056de5 drivers/firmware: psci_checker: stash and use topology_core_cpumask for hotplug tests
Commit 7f9545aa1a ("arm64: smp: remove cpu and numa topology
information when hotplugging out CPU") updates the cpu topology when
the CPU is hotplugged out. However the PSCI checker code uses the
topology_core_cpumask pointers for some of the cpu hotplug testing.
Since the pointer to the core_cpumask of the first CPU in the group
is used, which when that CPU itself is hotpugged out is just set to
itself, the testing terminates after that particular CPU is tested out.
But the intention of this tests is to cover all the CPU in the group.

In order to support that, we need to stash the topology_core_cpumask
before the start of the test and use that value instead of pointer to
a cpumask which will be updated on CPU hotplug.

Fixes: 7f9545aa1a ("arm64: smp: remove cpu and numa topology
	information when hotplugging out CPU")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
