commit357d065a44upstream. VMX ghash was using a fallback that did not support interleaving simd and nosimd operations, leading to failures in the extended test suite. If I understood correctly, Eric's suggestion was to use the same data format that the generic code uses, allowing us to call into it with the same contexts. I wasn't able to get that to work - I think there's a very different key structure and data layout being used. So instead steal the arm64 approach and perform the fallback operations directly if required.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
