To calculate the correct node to migrate the page for hotplug, we need to check node id of the page. Wrapper for alloc_migration_target() exists for this purpose. However, Vlastimil informs that all migration source pages come from a single node. In this case, we don't need to check the node id for each page and we don't need to re-set the target nodemask for each page by using the wrapper. Set up the migration_target_control once and use it for all pages.

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.
