I submitted the series to Russell's patch system on 9 April.
However, as you know, he's currently without an internet connection and
the patch system has gone offline. He applied some of the series before
he lost connectivity, so I expect he'll look at the others when he's
back [although I imagine there are lots of other patches in the same
situation].

Peter: if you're interested, the patch series I sent to the ARM
Linux list is archived here:

Cheers,

Will
