Hi Olof,
Now Linux 4.3-rc1 is out, so I am back to this.
1/3: add outer cache support
2/3: rework SMP operations
3/3: add device tree nodes
Because 2/3 highly depends on 1/3, I hope whole of this series
is applied through ARM-SOC tree.
Changes in v4:
- Add more detailed comments to explain why no spin lock is needed
- Add two examples to the binding document
Changes in v3:
- Drop bogus includes
Changes in v2:
- Use pr_fmt() to have pr_<level> are automatically prefixed
- Re-design to initialize the outer cache earlier in init_IRQ()
- Require DT properties such as "cacne-unified", "cache-size",
"cache-sets", "cache-size", "cache-line-size".
- Follow "next-level-cache" property to search further outer caches
