Shift of a LE value seems strange, probably meant to shift the cpu-order
variable as in the prvious section of the switch statement.

Add some casts to the LZO compression algorithm after they were removed
during cleanup and shouldn't have been.

This is a hybrid version of the patch to add the LZO1X compression
algorithm to the kernel.  Nitin and myself have merged the best parts of
the various patches to form this version which we're both happy with (and
are jointly signing off).

The performance of this version is equivalent to the original minilzo code
it was based on.  Bytecode comparisons have also been made on ARM, i386 and
x86_64 with favourable results.

There are several users of LZO lined up including jffs2, crypto and reiser4
since its much faster than zlib.
