In the slow path of skcipher_walk where it uses a slab bounce buffer for the data and/or IV, do not bother to avoid crossing a page boundary in the part(s) of this buffer that are used, and do not bother to allocate extra space in the buffer for that purpose. The buffer is accessed only by virtual address, so pages are irrelevant for it. This logic may have been present due to the physical address support in skcipher_walk, but that has now been removed. Or it may have been present to be consistent with the fast path that currently does not hand back addresses that span pages, but that behavior is a side effect of the pages being "mapped" one by one and is not actually a requirement.

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.
