Just two fixes, both going to stable.
Our support for split pmd page table lock had a bug which could lead to a crash
on mremap() when using the Radix MMU (Power9 only).
A fix for the PAPR SCM driver (nvdimm) we added last release, which had a bug
where we might mis-handle a hypervisor response leading to us failing to attach
the memory region.
Thanks to:

README
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.
