Due to this, the patch appends AVX2 transform to the build mix and leaves
the configuration build support as is.

Sorry, there seems to be a problem with the patch. Let me retest from
the list again and repost.

Subject: [PATCH v4 1/1] crypto: SHA1 transform x86_64 AVX2
This git patch adds x86_64 AVX2 optimization of SHA1
transform to crypto support. The patch
necessary objects to the linkage.
Due to this, the patch merely appends AVX2 transform to the existing build mix
and Kconfig support and leaves the configuration build support as is.
