[PATCH 00/14][RFC] Crypto keys and module signing

Here are a set of patches that create a framework for using cryptographic keys within the kernel. The basic crypto key has no requirements as to how the key is implemented; it's basically a jump table for the operations and an anchor for any relevant data. I have provided a couple of subtypes:

[PATCH 05/14] Misc cleanup of lib/crc32.c and related files

[PATCH 03/14] 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
