Aneesh Kumar K.V 9bd3bb6703 mm/nvdimm: add is_ioremap_addr and use that to check ioremap address
Architectures like powerpc use different address range to map ioremap
and vmalloc range.  The memunmap() check used by the nvdimm layer was
wrongly using is_vmalloc_addr() to check for ioremap range which fails
for ppc64.  This result in ppc64 not freeing the ioremap mapping.  The
side effect of this is an unbind failure during module unload with
papr_scm nvdimm driver

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.
