Jiajian Ye cf3c2c8678 tools/vm/page_owner_sort.c: support sorting by tgid and update documentation
When the "page owner" information is read, the information sorted
by TGID is expected.

As a result, the following adjustments have been made:

1. Add a new -P option to sort the information of blocks by TGID in
   ascending order.

2. Adjust the order of member variables in block_list strust to avoid
   one 4 byte hole.

3. Add -P option explanation in the document.

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.
