We've already gotten the stable locked folio in collapse_pte_mapped_thp(), so just use folio for set_huge_pmd() to set the PMD entry, which is more straightforward. Moreover, we will check the folio size in do_set_pmd(), so we can remove the unnecessary VM_BUG_ON() in set_huge_pmd(). While we are at it, we can also remove the PageTransHuge(), as it currently has no callers.

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 reStructuredText 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.
