The recent addition of the AVX2 variant of the SHA1 hash function wrongly disabled the AVX variant by introducing a flaw in the feature test. Fixed in patch 1.
The alignment calculations of the AVX2 assembler implementation are questionable, too. Especially the page alignment of the stack pointer is broken in multiple ways. Fixed in patch 2. In patch 3 another issue for code alignment is fixed. Please apply!
