I didn't intend to exclude anyone and I'm just reporting it, it didn't
came to my mind CC'ing people while sending to stable, and hopefully
everyone related are CC'ed now.

Also note that this revert request is for 2.6.32 and 2.6.33 *only*

And seems the right thing to do for them.

The other stable release where this was applied (2.6.35) looks fine
but these two are too old to support the new firmware (don't work, need
extra patches backported which weren't, like the commit I mentioned --
commit "iwlagn: implement loading a new firmware file type"), as yourself
can check reading the code/bug report, and what I wrote.
