If we don't hear from Russell by the end of today, I propose that we
merge patches 1-8 in the arm64 tree (mostly fixes for PSCI). This series
is blocking other developments like PSCI 1.0, so I really want to get
parts of it merged in 4.2.

BTW, can we skip patch 11 in this series and still allow
drivers/firmware/psci.c only for arm64, with the aim of moving the arm32
code later?

Thanks.
