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.

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.
