Introduce kref-based reference counting and spinlock protection for memory regions in Hyper-V partition management. This change improves memory region lifecycle management and ensures thread-safe access to the region list. Previously, the regions list was protected by the partition mutex. However, this approach is too heavy for frequent fault and invalidation operations. Finer grained locking is now used to improve efficiency and concurrency. This is a precursor to supporting movable memory regions. Fault and invalidation handling for movable regions will require safe traversal of the region list and holding a region reference while performing invalidation or fault operations.

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.
