Suzuki K Poulose f5e035f869 arm64: Expose support for optional ARMv8-A features ... ARMv8-A adds a few optional features for ARMv8.2 and ARMv8.3. Expose them to the userspace via HWCAPs and mrs emulation. SHA2-512 - Instruction support for SHA512 Hash algorithm (e.g SHA512H, SHA512H2, SHA512U0, SHA512SU1) SHA3 - SHA3 crypto instructions (EOR3, RAX1, XAR, BCAX). SM3 - Instruction support for Chinese cryptography algorithm SM3 SM4 - Instruction support for Chinese cryptography algorithm SM4 DP - Dot Product instructions (UDOT, SDOT).
