Subject: [PATCH] mtip32xx: Reduce the number of unaligned writes to 2
Date: Tue, 18 Feb 2014 13:46:51 -0800 [thread overview]

Hi Jens,
Please include this for 3.14. It is a trivial change, hope it should be ok.

After several experiments, deduced the the optimal number of unaligned
writes to be 2. Changing the value accordingly.
