commitf34ee9cb2cupstream. In the numa=off kernel command-line configuration init_chip_info() loops around the number of chips and attempts to copy the cpumask of that node which is NULL for all iterations after the first chip. Hence, store the cpu mask for each chip instead of derving cpumask from node while populating the "chips" struct array and copy that to the chips[i].mask Fixes:053819e0bf("cpufreq: powernv: Handle throttling due to Pmax capping at chip level") Cc: stable@vger.kernel.org # v4.3+ Reported-by: Shirisha Ganta <shirisha.ganta1@ibm.com> Signed-off-by: Pratik R.

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.
