This patch add basic arch initialization and instruction associate
support for the csky CPU architecture.
E.g.:
$ perf annotate --stdio2
Samples: 161 of event 'cpu-clock:pppH', 4000 Hz, Event count (approx.):
40250000, [percent: local period]
test_4() /usr/lib/perf-test/callchain_test

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.
