This patch adds declarations for variables only used by assembly code to silence compiler warnings: CC [M] arch/arm64/crypto/sha1-ce-glue.o AS [M] arch/arm64/crypto/sha1-ce-core.o CC [M] arch/arm64/crypto/sha2-ce-glue.o AS [M] arch/arm64/crypto/sha2-ce-core.o CHECK ../arch/arm64/crypto/sha1-ce-glue.c CHECK ../arch/arm64/crypto/sha2-ce-glue.c ../arch/arm64/crypto/sha1-ce-glue.c:38:11: warning: symbol 'sha1_ce_offsetof_count' was not declared.

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.
