Some arch configs (like ppc64) enable CONFIG_PRINTK_CALLER,
which adds the caller id as part of the dmesg. With recent
util-linux's update 467a5b3192f16 ('dmesg: add caller_id support')
the standard "dmesg" has been enhanced to print PRINTK_CALLER fields.
Due to this, even though the expected vs observed are same,
end testcase results are failed.

Currently the check_result() handles the "[time]" removal from
the dmesg. Enhance the check to also handle removal of "[Thread Id]"
or "[CPU Id]".

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 reStructuredText 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.
