As the only user of acomp/scomp uses a trivial single-page SG list, remove support for everything else in preprataion for the addition of virtual address support. However, keep support for non-trivial source SG lists as that user is currently jumping through hoops in order to linearise the source data. Limit the source SG linearisation buffer to a single page as that user never goes over that. The only other potential user is also unlikely to exceed that (IPComp) and it can easily do its own linearisation if necessary. Also keep the destination SG linearisation for IPComp.

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.
