Commit667416f385("powerpc/mm: Fix kernel crash on page table free") added a call for pgtable_page_dtor in the rcu page table free routine. We missed the fact that for 32 bit platforms we did call the 'dtor' early. Drop the extra call for pgtable_page_dtor. We remove the call from __pte_free_tlb so that we do the page table free and 'dtor' call together. This should help when we switch these platforms to pte fragments.

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.
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.
