	  Some VIA processors come with an integrated crypto engine
	  (so called VIA PadLock ACE, Advanced Cryptography Engine)
	  that provides instructions for very fast cryptographic
	  operations with supported algorithms.

	  The instructions are used only when the CPU supports them.
	  Otherwise software encryption is used.

	  Select this option if you want to enable support for

	  or Accelerator (CEXxA) mode.

config PKEY
	tristate "Kernel API for protected key handling"
	depends on S390
	help
	  With this option enabled the pkey kernel modules provide an API
	  for creation and handling of protected keys. Other parts of the
	  kernel or userspace applications may use these functions.

	  The protected key support is distributed into:
	  - A pkey base and API kernel module (pkey.ko) which offers the
	    infrastructure for the pkey handler kernel modules, the ioctl
	    and the sysfs API and the in-kernel API to the crypto cipher
	    implementations using protected key.
	  - A pkey pckmo kernel module (pkey-pckmo.ko) which is automatically
	    loaded when pckmo support (that is generation of protected keys
	    from clear key values) is available.
	  - A pkey CCA kernel module (pkey-cca.ko) which is automatically
	    loaded when a CEX crypto card is available.
	  - A pkey EP11 kernel module (pkey-ep11.ko) which is automatically
	    loaded when a CEX crypto card is available.
	  - A pkey UV kernel module (pkey-uv.ko) which is automatically
	    loaded when the Ultravisor feature is available within a
	    protected execution environment.

	  Select this option if you want to enable the kernel and userspace
	  API for protected key handling.

	help
	  This is the CCA support handler for deriving protected keys
	  from CCA (secure) keys. Also this handler provides an alternate
	  way to make protected keys from clear key values.

	  The PKEY CCA support handler needs a Crypto Express card (CEX)
	  in CCA mode.

	  If you have selected the PKEY option then you should also enable
	  this option unless you are sure you never need to derive protected
	  keys from CCA key material.

config PKEY_EP11

	depends on PKEY
	depends on ZCRYPT
	help
	  This is the EP11 support handler for deriving protected keys
	  from EP11 (secure) keys. Also this handler provides an alternate
	  way to make protected keys from clear key values.

	  The PKEY EP11 support handler needs a Crypto Express card (CEX)
	  in EP11 mode.

	  If you have selected the PKEY option then you should also enable
	  this option unless you are sure you never need to derive protected
	  keys from EP11 key material.

config PKEY_PCKMO
	tristate "PKEY PCKMO support handler"
	depends on PKEY
	help
	  This is the PCKMO support handler for deriving protected keys
	  from clear key values via invoking the PCKMO instruction.

	  The PCKMO instruction can be enabled and disabled in the crypto
	  settings at the LPAR profile. This handler checks for availability
	  during initialization and if build as a kernel module unloads
	  itself if PCKMO is disabled.

	  The PCKMO way of deriving protected keys from clear key material
	  is especially used during self test of protected key ciphers like
	  PAES but the CCA and EP11 handler provide alternate ways to
	  generate protected keys from clear key values.

	  If you have selected the PKEY option then you should also enable
	  this option unless you are sure you never need to derive protected
	  keys from clear key values directly via PCKMO.

config PKEY_UV
	tristate "PKEY UV support handler"
	depends on PKEY
	depends on S390_UV_UAPI
	help
	  This is the PKEY Ultravisor support handler for deriving protected
	  keys from secrets stored within the Ultravisor (UV).

	  This module works together with the UV device and supports the
	  retrieval of protected keys from secrets stored within the
	  UV firmware layer. This service is only available within
	  a protected execution guest and thus this module will fail upon
	  modprobe if no protected execution environment is detected.

	  Enable this option if you intend to run this kernel with an KVM
	  guest with protected execution and you want to use UV retrievable
	  secrets via PKEY API.

	  for example to use protected key encrypted devices.

config S390_PRNG
	tristate "Pseudo random number generator device driver"

	default "m"
	help
	  Select this option if you want to use the s390 pseudo random number
	  generator. The PRNG is part of the cryptographic processor functions
	  and uses triple-DES to generate secure random numbers like the
	  ANSI X9.17 standard. User-space programs access the
