This mostly reverts commit a0fc20333e.
Keep the relevant parts of the comment added by that commit.
The problem with that commit is that it allowed people to create broken
configurations that enabled FS_ENCRYPTION but not the mandatory
algorithms. An example of this can be found here:
https://lore.kernel.org/r/1207325.1737387826@warthog.procyon.org.uk/
The commit did allow people to disable specific generic algorithm
implementations that aren't needed. But that at best allowed saving a
bit of code. In the real world people are unlikely to intentionally and
correctly make such a tweak anyway, as they tend to just be confused by
what all the different crypto kconfig options mean.
Of course we really need the crypto API to enable the correct
implementations automatically, but that's for a later fix.

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.
