Jonathan Cameron f44c27d124 ACPI: processor: Fix memory leaks in error paths of processor_add() 
[ Upstream commit 47ec9b417e ]

If acpi_processor_get_info() returned an error, pr and the associated
pr->throttling.shared_cpu_map were leaked.

The unwind code was in the wrong order wrt to setup, relying on
some unwind actions having no affect (clearing variables that were
never set etc).  That makes it harder to reason about so reorder
and add appropriate labels to only undo what was actually set up
in the first place.

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.
