When the compiler chooses to not inline sha256_choose_blocks() in
the purgatory code, it fails to link against the missing CPU
specific version:
x86_64-linux-ld: arch/x86/purgatory/purgatory.ro: in function `sha256_choose_blocks.part.0':
sha256.c:(.text+0x6a6): undefined reference to `irq_fpu_usable'
sha256.c:(.text+0x6c7): undefined reference to `sha256_blocks_arch'
sha256.c:(.text+0x6cc): undefined reference to `sha256_blocks_simd'
Mark this function as __always_inline to prevent this, same as sha256_finup().
Fixes: 5b90a779bc ("crypto: lib/sha256 - Add helpers for block-based shash")

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.
