config CRC_CCITT
	tristate "CRC-CCITT functions"
	help
	  This option is provided for the case where no in-kernel-tree
	  modules require CRC-CCITT functions, but a module built outside
	  the kernel tree does. Such modules that use library CRC-CCITT
	  functions require M here.

	  This option is provided for the case where no in-kernel-tree
	  modules require CRC16 functions, but a module built outside
	  the kernel tree does. Such modules that use library CRC16
	  functions require M here.

config CRC_T10DIF
	tristate "CRC calculation for the T10 Data Integrity Field"
	help
	  This option is only needed if a module that's not in the
	  kernel tree needs to calculate CRC checks for use with the
	  SCSI data integrity subsystem.

config CRC_ITU_T
	tristate "CRC ITU-T V.41 functions"
	help
	  This option is provided for the case where no in-kernel-tree

	  This option is provided for the case where no in-kernel-tree

	  kernel tree does. Such modules that use library CRC32 functions
	  require M here.

	  This option is provided for the case where no in-kernel-tree
	  modules require CRC7 functions, but a module built outside

	  require M here.  See Castagnoli93.

	  Use dynamic allocation for cpumask_var_t, instead of putting
