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

	  This option enables the CRC32 library functions to perform a

	  and crc32_be over byte strings with random alignment and length
	  and computes the total elapsed time and number of bytes processed.

	default CRC32_SLICEBY8
	help
	  This option allows a kernel builder to override the default choice
	  of CRC32 algorithm.  Choose the default ("slice by 8") unless you
	  know that you need one of the others.

config CRC32_SLICEBY8
	bool "Slice by 8 bytes"
	help
	  Calculate checksum 8 bytes at a time with a clever slicing algorithm.
	  This is the fastest algorithm, but comes with a 8KiB lookup table.
	  Most modern processors have enough cache to hold this table without
	  thrashing the cache.

	  This is the default implementation choice.  Choose this one unless
	  you have a good reason not to.

config CRC32_SLICEBY4
	bool "Slice by 4 bytes"
	help
	  Calculate checksum 4 bytes at a time with a clever slicing algorithm.
	  This is a bit slower than slice by 8, but has a smaller 4KiB lookup
	  table.

	  Only choose this option if you know what you are doing.

config CRC32_SARWATE
	bool "Sarwate's Algorithm (one byte at a time)"
	help
	  Calculate checksum a byte at a time using Sarwate's algorithm.  This
	  is not particularly fast, but has a small 256 byte lookup table.

	  Only choose this option if you know what you are doing.

config CRC32_BIT
	bool "Classic Algorithm (one bit at a time)"
	help
	  Calculate checksum one bit at a time.  This is VERY slow, but has
	  no lookup table.  This is provided as a debugging option.

	  Only choose this option if you are debugging crc32.

	  Module will be libcrc32c.

config BCH_CONST_PARAMS
	boolean
	help
	  Drivers may select this option to force specific constant
	  values for parameters 'm' (Galois field order) and 't'
	  (error correction capability). Those specific values must
	  be set by declaring default values for symbols BCH_CONST_M
	  and BCH_CONST_T.
	  Doing so will enable extra compiler optimizations,
	  improving encoding and decoding performance up to 2x for
	  usual (m,t) values (typically such that m*t < 200).
	  When this option is selected, the BCH library supports
	  only a single (m,t) configuration. This is mainly useful
	  for NAND flash board drivers requiring known, fixed BCH
	  parameters.

config BCH_CONST_M
	int
	range 5 15
	help
	  Constant value for Galois field order 'm'. If 'k' is the
	  number of data bits to protect, 'm' should be chosen such
	  that (k + m*t) <= 2**m - 1.
	  Drivers should declare a default value for this symbol if
	  they select option BCH_CONST_PARAMS.

config BCH_CONST_T
	int
	help
	  Constant value for error correction capability in bits 't'.
	  Drivers should declare a default value for this symbol if

config INTERVAL_TREE

	  Simple, embeddable, interval-tree. Can find the start of an

	  overlapping nodes. The algorithm is implemented as an
	  augmented rbtree.

	  See:

		Documentation/rbtree.txt

	  for more information.

config ASSOCIATIVE_ARRAY
	bool
	help
	  Generic associative array.  Can be searched and iterated over whilst
	  it is being modified.  It is also reasonably quick to search and
	  modify.  The algorithms are non-recursive, and the trees are highly
	  capacious.
