Compare and branch, pause, and the various new cryptographic opcodes. We advertise the crypto opcodes to userspace using one hwcap bit, HWCAP_SPARC_CRYPTO. This essentially indicates that the %cfr register can be interrograted and used to determine exactly which crypto opcodes are available on the current cpu. We use the %cfr register to report all of the crypto opcodes available in the bootup CPU caps log message, and via /proc/cpuinfo. Signed-off-by: David S. Miller <davem@davemloft.net>
