Christoph Hellwig 30bf04bd13 raid6: update top of file comments 
Drop the pointless mention of the file name, and use standard formatting
for the top of file comments.

Christoph Hellwig adfcf6e89b raid6: rework registration of optimized algorithms 
Replace the static array of algorithms with a call to an architecture
helper to register algorithms.  This serves two purposes: it avoid having
to register all algorithms in a single central place, and it removes the
need for the priority field by just registering the algorithms that the
architecture considers suitable for the currently running CPUs.

Christoph Hellwig 769d603fc4 raid6: hide internals 
Split out two new headers from the public pq.h:

 - lib/raid/raid6/algos.h contains the algorithm lists private to
   lib/raid/raid6
 - include/linux/raid/pq_tables.h contains the tables also used by
   async_tx providers.

The public include/linux/pq.h is now limited to the public interface for
the consumers of the RAID6 PQ API.

Christoph Hellwig 35472bc6f3 raid6: improve the public interface 
Stop directly calling into function pointers from users of the RAID6 PQ
API, and provide exported functions with proper documentation and API
guarantees asserts where applicable instead.

Christoph Hellwig 3626738bc7 raid6: move to lib/raid/ 
Move the raid6 code to live in lib/raid/ with the XOR code, and change the
internal organization so that each architecture has a subdirectory similar
to the CRC, crypto and XOR libraries, and fix up the Makefile to only
build files actually needed.

Also move the kunit test case from the history test/ subdirectory to
tests/ and use the normal naming scheme for it.
