Subject[PATCH v9 00/13] Per sub-architecture SMP operations
Date
As I promised at the ARM mini summit, I've updated Marc's series
for smp operations according to my complaints. Unfortunately,
I could not find version 7 of the patches when I started this,
so I based my work on version 6 and had to redo the same
changes.

The patches are also available on

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git testing/smp_ops

Arnd

Changelog:
From v8:
- removed the string concatenating macros
- consolidated structures into a single smp_operations
- removed trivial instances of platform_cpu_kill and
platform_cpu_disable, now handled by the default case
- split shmobile_cpu_kill into three separate functions,
per soc

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.

Arnd Bergmann (1):
ARM: SoC: convert spear13xx to SoC descriptor

Marc Zyngier (12):
ARM: SoC: add per-platform SMP operations
ARM: SoC: convert VExpress/RealView to SoC descriptor
ARM: SoC: convert OMAP4 to SoC descriptor
ARM: SoC: convert Tegra to SoC descriptor
ARM: SoC: convert Exynos4 to SoC descriptor
ARM: SoC: convert MSM SMP to SoC descriptor
ARM: SoC: convert ux500 to SoC descriptor
ARM: SoC: convert shmobile SMP to SoC descriptor
ARM: SoC: convert highbank to SoC descriptor
ARM: SoC: convert imx6q to SoC descriptor
ARM: smp: Make SoC descriptor mandatory for SMP platforms
ARM: consolidate pen_release instead of having per platform
