[As per Arnd request, I've updated this patch series, in the hope that
it could be useful to the single zImage work]

This patch series introduces a per-soc descriptor which should, in the
end, contain most of the SoC specific operations.

This first patch series introduces the arm_soc_desc structure, adds
per-soc SMP and CPU hotplug operations, and converts all SMP platform
to this new scheme.

Patches against v3.5-rc1. Tested on VExpress (Cortex A15).

Also available at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git soc_desc-v3.5-rc1

Changelog:

From v6:
- Dropped the dummy_* stuff
- Support for a number of new platforms
- Added the soc_hotplug_ops() macro to hide some #ifdef-ery away
- More exynos[ 45] churn
- Fixed section mismatches

From v5:
- Added support for highbank and imx6q
- Added support for new shmobile SMP platform
- Add dummy_cpu_kill, dummy_cpu_disable and cpu_lowpower

From v4:
- Added an SMP registration interface and moved all SMP structures to
  smp.c. The end result is much cleaner.
- Cleaned up patch 2 (leftovers from a previous rework)
- NVIDIA/EXYNOS4 naming cleanup.

From v3:
- Converted all SMP platforms
- Added some cleanup as a last patch

From v2:
- Split the SMP ops between init and runtime operations in order to
  have separate lifetimes for the different structures. This is not
  perfect though, as it still allows an __init function to make it to
  a runtime structure (all smp_*_ops structures are __initdata in
  order to be able to discard them). Thanks to Nico for pointing this
  out.
- Use macros to hide the #ifdef-ery in the SoC descriptor init,
  courtesy of Arnd.

From v1:
- Move the SMP ops out of the descriptor, which makes the structure
  init a bit cleaner (thanks to Arnd).
- Mark all structures __initdata and keep a copy of the used ones.
- Keep a global pointer for the SMP ops.
