Patch series "mm/pageblock: improve readability of some pageblock
handling", v3.
During code reading, found two possible points to improve the readability
of pageblock handling.
Patch 1: isolate bit is standalone and there are dedicated helpers.
Instead of check the bit directly, we could use the helper to do it.
Patch 2: remove PB_migratetype_bits and PB_migrate_end to reduce magical
computation.
This patch (of 2):
Since commit e904bce2d9 ("mm/page_isolation: make page isolation a
standalone bit"), it provides dedicated helper to handle isolation.
Change to use these helpers to be better reading.
No functional change intended.

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.
