Let's use folio_add_anon_rmap_ptes(), batching the rmap operations. While at it, use more folio operations (but only in the code branch we're touching), use VM_WARN_ON_FOLIO(), and pass RMAP_EXCLUSIVE instead of manually setting PageAnonExclusive. We should never see non-anon pages on that branch: otherwise, the existing page_add_anon_rmap() call would have been flawed already.

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.
