[PATCH] crypto: arm64/crc32 - merge CRC32 and PMULL instruction based drivers

2017-02-01 Thread Ard Biesheuvel
The PMULL based CRC32 implementation already contains code based on the separate, optional CRC32 instructions to fallback to when operating on small quantities of data. We can expose these routines directly on systems that lack the 64x64 PMULL instructions but do implement the CRC32 ones, which
