[PATCH v8 00/13] Per sub-architecture SMP operations

This patch series is a small departure from the earlier series, which
was trying to introduce a SoC descriptor. Instead, this one focusses
on SMP operations, and only this, as per Arnd's request.
Each platforms exports a "struct smp_ops" that is pointed to by their
mach_desc. The last patch consolidates the definition of pen_release
into the SMP code, though this is arguably wrong (most platforms
shouldn't need the whole pen_release thing at all).
Patches against v3.5-rc2. Tested on VExpress (Cortex A15).

Changelog:
>From v7:
- Dropped soc_desc, and focussed only on smp_ops
- Fixed CONFIG_HOTPLUG_CPU typo (courtesy of Shawn Guo)
- Marked {realview,vexpress}_cpu_die() as __cpuinit
- Added support for spear13xx
- Added pen_release consolidation (based on Arnd Bergman's patch)
>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.
