Aneesh Kumar K.V ac25ba68fa powerpc/mm/hugetlb: Don't enable HugeTLB if we don't have a page table cache
This makes sure we don't enable HugeTLB if the cache is not configured.
I am still not sure about this. IMHO hugetlb support should be a hardware
support derivative and any cache allocation failure should be handled as I did
in the earlier patch. But then if we were not able to create hugetlb page table
cache, we can as well declare hugetlb support disabled thereby avoiding calling
into allocation routines.

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.
