*	lib: crc32: Add some additional __pure annotations	George Spelvin	2014-06-25	1	-3/+3

*	lib: crc32: Greatly shrink CRC combining code	George Spelvin	2014-06-25	1	-2/+12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	There's no need for a full 32x32 matrix, when rows before the last are just shifted copies of the rows after them. There's still room for improvement (especially on X86 processors with CRC32 and PCLMUL instructions), but this is a large step in the right direction [which is in particular useful for its current user, namely SCTP checksumming over multiple skb frags[] entries, i.e. in IPVS balancing when other CRC32 offloads are not available]. The internal primitive is now called crc32_generic_shift and takes one less argument; the XOR with crc2 is done in inline wrappers.

*	lib: crc32: add functionality to combine two crc32{, c}s in GF(2)	Daniel Borkmann	2013-11-03	1	-0/+40
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds a combinator to merge two or more crc32{,c}s into a new one. This is useful for checksum computations of fragmented skbs that use crc32/crc32c as checksums. The arithmetics for combining both in the GF(2) was taken and slightly modified from zlib. Only passing two crcs is insufficient as two crcs and the length of the second piece is needed for merging. The code is made generic, so that only polynomials need to be passed for crc32_le resp. crc32c_le.

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-16	1	-0/+27
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
