Cédric Le Goater 8e036c8d30 powerpc/xive: Use hw CPU ids when configuring the CPU queues
The CPU event notification queues on sPAPR should be configured using
a hardware CPU identifier.

The problem did not show up on the Power Hypervisor because pHyp
supports 8 threads per core which keeps CPU number contiguous. This is
not the case on all sPAPR virtual machines, some use SMT=1.

Also improve error logging by adding the CPU number.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
