Sidhartha Kumar 4a3ef6be03 mm/hugetlb: have CONFIG_HUGETLB_PAGE select CONFIG_XARRAY_MULTI 
After commit a08c7193e4 "mm/filemap: remove hugetlb special casing in
filemap.c", hugetlb pages are stored in the page cache in base page sized
indexes.  This leads to multi index stores in the xarray which is only
supporting through CONFIG_XARRAY_MULTI.  The other page cache user of
multi index stores ,THP, selects XARRAY_MULTI.  Have CONFIG_HUGETLB_PAGE
follow this behavior as well to avoid the BUG() with a CONFIG_HUGETLB_PAGE
&& !CONFIG_XARRAY_MULTI config.

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.
