Convert tls_device_sendpage() to use sendmsg() with MSG_SPLICE_PAGES rather than directly splicing in the pages itself. With that, the tls_iter_offset union is no longer necessary and can be replaced with an iov_iter pointer and the zc_page argument to tls_push_data() can also be removed. This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction.

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.
