POLYVAL hash function for HCTR2

Architecture: x86_64 using: - CLMUL-NI (carry-less multiplication new instructions)

POLYVAL hash function (CLMUL-NI accelerated) found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_POLYVAL_CLMUL_NI:

• prompt: POLYVAL hash function (CLMUL-NI accelerated)
• type: tristate
• depends on: CONFIG_X86 && CONFIG_64BIT
• defined in crypto/Kconfig
• found in Linux kernels: 6.0, 6.0+HEAD
• modules built: polyval-clmulni, polyval-clmulni

Help text

This is the x86_64 CLMUL-NI accelerated implementation of POLYVAL. It is used to efficiently implement HCTR2 on x86-64 processors that support carry-less multiplication instructions.
