87	  - A pkey base and API kernel module (pkey.ko) which offers the
88	    infrastructure for the pkey handler kernel modules, the ioctl
89	    and the sysfs API and the in-kernel API to the crypto cipher
90	    implementations using protected key.

142	  settings at the LPAR profile. This handler checks for availability
143	  during initialization and if build as a kernel module unloads
144	  itself if PCKMO is disabled.
145
146	  The PCKMO way of deriving protected keys from clear key material
147	  is especially used during self test of protected key ciphers like
148	  PAES but the CCA and EP11 handler provide alternate ways to
149	  generate protected keys from clear key values.
150
