Miaohe Lin ebddd111fc mm/page_alloc: avoid unneeded alike_pages calculation
When free_pages is 0, alike_pages is not used.  So alike_pages calculation
can be avoided by checking free_pages early to save cpu cycles.  Also fix
typo 'comparable'.  It should be 'compatible' here.

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.
