crc32-move-to-documentation

Moved a long comment from lib/crc32.c to Documentation/crc32.txt
where it will more likely get read.
	- Edited the resulting document to add an explanation of the slicing-by-n

crc32-replace-self-test

Replaced the unit test provided in crc32.c, which doesn't have a
makefile and doesn't compile with current headers, with a simpler
self test routine that also gives a measure of performance and
runs at module init time. The self test option can be enabled
through a configuration option CONFIG_CRC32_SELFTEST.

The test stresses the pre and post loops and is thus not very
realistic since actual uses will likely have addresses and lengths
that are at least 4 byte aligned. However, the main loop is long
enough so that the performance is dominated by that loop.

The expected values for crc32_le and crc32_be were generated
with the original version of crc32.c using CRC_BITS_LE = 8 and
CRC_BITS_BE = 8. These values were then used to check all the
values of the BITS parameters in both the original and new versions.

The performance results show some variability from run to run
in spite of attempts to both warm the cache and reduce the amount
of OS noise by limiting interrutps during the test. To get comparable
results and to analyse options wrt performance the best time
reported over a small sample of runs has been taken.

crc32-add-pointer-to-tab

Replace 2D array references by pointer references in loops.
This change has no effect on X86 code but improves PPC
performance.

crc32-misc-cleanup

Misc cleanup of lib/crc32.c and related files
	- removed unnecessary header files.
	- straightened out some convoluted ifdef's
	- rewrote some references to 2 dimensional arrays as 1 dimensional
	  arrays to make them correct. I.e. replaced tab[i] with tab[0][i].
	- a few trivial whitespace changes
	- fixed a warning in gen_crc32tables.c caused by a mismatch in the
	  type of the pointer passed to output table. Since the table is
	  only used at kernel compile time, it is simpler to make the table
	  big enough to hold the largest column size used. One cannot make the
	  column size smaller in output_table because it has to be used by
	  both the le and be tables and they can have different column sizes.

crc32-fix-check-endian-warnings

crc32.c in its original version freely mixed u32, __le32 and __be32 types
which caused warnings from sparse with __CHECK_ENDIAN__.
This patch fixes these by forcing the types to u32.

crc32-add-real-8-bit

crc32.c provides a choice of one of several algorithms for
computing the LSB and LSB versions of the CRC32 checksum
based on the parameters CRC_LE_BITS and CRC_BE_BITS. In the
original version the values 1, 2, 4 and 8 respectively selected
versions of the alrogithm that computed the crc 1, 2, 4 and 32
bits as a time. This patch series adds a new version that computes
the CRC 64 bits at a time. To make things easier to understand
the parameter has been reinterpreted to actually stand for the
number of bits processed in each step of the algorithm so that
the old value 8 has been replaced with the value 32. This also
allows us to add in a widely used crc algorithm that
computes the crc 8 bits at a time called the Sarwate algorithm.

crc32-add-slicing-by-8

add slicing-by-8 algorithm to the existing
slicing-by-4 algorithm. This consists of:
	- extend largest BITS size from 32 to 64
	- extend tables from tab[4][256] to up to tab[8][256]
	- Add code for inner loop.

crc32-optimize-loops

Add two changes that improve the performance of x86 systems
	1. replace main loop with incrementing counter
	   this change improves the performance of the selftest
	   by about 5-6% on Nehalem CPUs. The apparent
	   reason is that the compiler can use the loop index
	   to perform an indexed memory access. This is
	   reported to make the performance of PowerPC CPUs
	   to get worse.
	2. replace the rem_len loop with incrementing counter
	   this change improves the performance of the selftest,
	   which has more than the usual number of occurances,
	   by about 1-2% on x86 CPUs. In actual work loads
	   the length is most often a multiple of 4 bytes and
	   this code does not get executed as often if at all.
	   Again this change is reported to make the performance
	   of PowerPC get worse.
