Subject: [PATCH v2 0/6] i.MX L2-cache code cleanups and performance tweaks

Hi everyone,

Here's the second version of i.MX L2-cache related patches. Here's
what's new from v1:

 - Already existing, spelling error free (shame on me for not noticing
   that in previous version!), symbolic constant defintions are used

 - Increased scope of magic number replacement (additional instance in
   cache-l2x0.c)

 - Added patch to remove unnecessary bit clearing in cache-l2x0.c

 - Added patch to implement a cleanup as suggested by Arnd

 - Added patch to tweak prefetch settings to improve performance. I
   was originally going to post this patch separately. But now that
   there was a need for v2, I decided to include it in the series.

All the feedback is much appreciated.

Thank you,
Andrey Smirnov
