Add madvise collapse context to hugepage collapse selftests. This context is tested with /sys/kernel/mm/transparent_hugepage/enabled set to "never" in order to avoid unwanted interaction with khugepaged during testing. Also, refactor updates to sysfs THP settings using a stack so that the THP settings from nested callers can be restored.

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.
