Add regression and new tests when hugepage has correctable memory errors, and how userspace wants to deal with it: * if enable_soft_offline=1, mapped hugepage is soft offlined * if enable_soft_offline=0, mapped hugepage is intact Free hugepages case is not explicitly covered by the tests. Hugepage having corrected memory errors is emulated with MADV_SOFT_OFFLINE.

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.
