Now that make_folio_secure() may only set PG_arch_1 for small folios, let's convert relevant remaining UV code to only work on (small) folios and simply reject large folios early. This way, we'll never end up touching PG_arch_1 on tail pages of a large folio in UV code. The folio_get()/folio_put() for functions that are documented to already hold a folio reference look weird; likely they are required to make concurrent gmap_make_secure() back off because the caller might only hold an implicit reference due to the page mapping. So leave that alone for now.

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.
