[ Upstream commit 3b1313eb32 ]
Report L1 caches as shared per core; L2 - per cluster.
This fixes "perf" that went crazy if shared_cpu_map attribute not
reported on sysfs, in form of
/sys/devices/system/cpu/cpu*/cache/index*/shared_cpu_list
/sys/devices/system/cpu/cpu*/cache/index*/shared_cpu_map

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.
