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.
config CRC16
tristate "CRC16 functions"
help
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"
select CRYPTO
select CRYPTO_CRCT10DIF
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
modules require CRC ITU-T V.41 functions, but a module built outside
the kernel tree does. Such modules that use library CRC ITU-T V.41
functions require M here.
config CRC32
tristate "CRC32/CRC32c functions"

select BITREVERSE
help
This option is provided for the case where no in-kernel-tree
modules require CRC32/CRC32c functions, but a module built outside
the kernel tree does. Such modules that use library CRC32/CRC32c
functions require M here.
config CRC32_SELFTEST
bool "CRC32 perform self test on init"
default n
depends on CRC32
help
This option enables the CRC32 library functions to perform a
self test on initialization. The self test computes crc32_le
and crc32_be over byte strings with random alignment and length
and computes the total elapsed time and number of bytes processed.
config CRC7
tristate "CRC7 functions"
help
This option is provided for the case where no in-kernel-tree
modules require CRC7 functions, but a module built outside
the kernel tree does. Such modules that use library CRC7
functions require M here.

help
This option is provided for the case where no in-kernel-tree
modules require CRC32c functions, but a module built outside the
kernel tree does. Such modules that use library CRC32c functions
require M here. See Castagnoli93.
Module will be libcrc32c.

help
Simple, embeddable, interval-tree. Can find the start of an
overlapping range in log(n) time and then iterate over all
overlapping nodes. The algorithm is implemented as an
augmented rbtree.
See:

help
Use dynamic allocation for cpumask_var_t, instead of putting
them on the stack. This is a bit more expensive, but avoids
stack overflow.

config CORDIC
tristate "Cordic function"
help
The option provides arithmetic function using cordic algorithm
so its calculations are in fixed point. Modules can select this
when they require this function. Module will be called cordic.
