[GIT PULL] ARM: MPIDR linearization

[Lorenzo Pieralisi]

Hi Russell,

please pull this patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume} code to
use the newly created hash structures to retrieve context pointers.
It represents a stepping stone for the implementation of power management code
on forthcoming multi-cluster ARM systems.

It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and
Tegra, with processors hitting low-power states requiring warm-boot resume
through the cpu_resume code path.

It is rebased against your devel-stable, I fixed conflicts with code already
queued there.

Please let me know if you have any objection.

Thank you very much indeed,
Lorenzo
