Hi Christoph,

I saw you sent this patch as part of another series back in August, but
it seems it was never applied and I can't find it even in -next. We made
some tests and this patch is helping a lot the PPv2 engine driver in
improving its performances.

Do you plan on re-sending it, or reworking it? Are there current issues
with it that prevent it from being merged upstream? Can we help in any
way?

Hi Antoine,

it's been a while, but my vague memory is that this caused failures
in some ARM setups, and I was tought why for AMBA setting up the
default mask is a bad idea.  I don't really remember more, though.
