'Idle page tracking' users can pass random pfn that might be mapped to an offline page. To avoid accessing such pages, this commit modifies the 'page_idle_get_page()' to use 'pfn_to_online_page()' instead of 'pfn_valid()' and 'pfn_to_page()' combination, so that the pfn mapped to an offline page can be skipped.

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.
