Jiri Olsa 14a9769a76 perf env: Add perf_env__numa_node()
[ Upstream commit 389799a7a1e86c55f38897e679762efadcc9dedd ]

To speed up cpu to node lookup, add perf_env__numa_node(), that creates
cpu array on the first lookup, that holds numa nodes for each stored
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.

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.
