Pull libnvdimm fixes from Dan Williams:
"Two regression fixes, two bug fixes for older issues, two fixes for
new functionality added this cycle that have userspace ABI concerns,
and a small cleanup. These have appeared in a linux-next release and
have a build success report from the 0day robot.
* The 4.16 rework of altmap handling led to some configurations
leaking page table allocations due to freeing from the altmap
reservation rather than the page allocator.
The impact without the fix is leaked memory and a WARN() message
when tearing down libnvdimm namespaces. The rework also missed a
place where error handling code needed to be removed that can lead
to a crash if devm_memremap_pages() fails.
* acpi_map_pxm_to_node() had a latent bug whereby it could
misidentify the closest online node to a given proximity domain.
* Block integrity handling was reworked several kernels back to allow
calling add_disk() after setting up the integrity profile.
The nd_btt and nd_blk drivers are just now catching up to fix
automatic partition detection at driver load time.
* The new peristence_domain attribute, a platform indicator of
whether cpu caches are powerfail protected for example, is meant to
be a single value enum and not a set of flags.
This oversight was caught while reviewing new userspace code in
libndctl to communicate the attribute.
Fix this new enabling up so that we are not stuck with an unwanted
userspace ABI"

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
