commit0a9567ac5eupstream. Moving mem_encrypt_init() broke the AMD_MEM_ENCRYPT=n because the declaration of that function was under #ifdef CONFIG_AMD_MEM_ENCRYPT and the obvious placement for the inline stub was the #else path. This is a leftover of commit20f07a044a("x86/sev: Move common memory encryption code to mem_encrypt.c") which made mem_encrypt_init() depend on X86_MEM_ENCRYPT without moving the prototype. That did not fail back then because there was no stub inline as the core init code had a weak function. Move both the declaration and the stub out of the CONFIG_AMD_MEM_ENCRYPT section and guard it with CONFIG_X86_MEM_ENCRYPT.

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.
