I did not and do not see significant value in
adding LZ4 given Markus' LZO improvements.
Please someone post a comprehensive comparison with all the results in
the same email.

The new LZO code is faster than ever and it's
a standalone improvement.

Why would the LZO code not be updated?
It is used by filesystems, etc. So of course it needs to be updated to
faster code.

Markus has posted what seems a clean git pull
request. It was not cc'd to arm or linux-arch.

Maybe a reminder should be sent to Linus about this.

From the above we can see this:

**LZO-2013-UA : updated LZO version available in linux-next plus
experimental ARM Unaligned Access patch. This needs approval from
some ARM maintainer ist NOT YET INCLUDED.

What is that experimental patch in need of approval?
