Kan Liang 61e51bae83 perf evlist: Always use arch_evlist__add_default_attrs() 
[ Upstream commit a9c1ecdabc ]

Current perf stat uses the evlist__add_default_attrs() to add the
generic default attrs, and uses arch_evlist__add_default_attrs() to add
the Arch specific default attrs, e.g., Topdown for x86.

It works well for the non-hybrid platforms. However, for a hybrid
platform, the hard code generic default attrs don't work.

Uses arch_evlist__add_default_attrs() to replace the
evlist__add_default_attrs(). The arch_evlist__add_default_attrs() is
modified to invoke the same __evlist__add_default_attrs() for the
generic default attrs. No functional change.

Add default_null_attrs[] to indicate the arch specific attrs.
No functional change for the arch specific default attrs either.

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.
