Taken from Paul Burton MIPS repo with minor changes from Chao-ying Fu.
Tested with 64r6el_defconfig on Boston board in 2 cluster/2 VPU and
1 cluster/4 VPU configurations.
v6:
- Re-base onto the master branch, with no functionality impact.
- Correct the issue reported by the kernel test robot.
v5:
- Drop FDC related changes (patches 12, 13, and 14).
- Apply changes suggested by Thomas Gleixner (patches 3 and 4).
- Add #include <linux/cpumask.h> to patch 1, suggested by Thomas Bogendoerfer.
- Add Reviewed-by: Philippe Mathieu-Daudé <philmd@xxxxxxxxxx> for the patch 08/11.
- Add Tested-by: Serge Semin <fancer.lancer@xxxxxxxxx> for the entire series.
- Correct some commit messages.
v4:
- Re-base onto the master branch, with no functionality impact.
- Refactor MIPS FDC driver in the context of multicluster support.
v3:
- Add Reviewed-by: Jiaxun Yang <jiaxun.yang@xxxxxxxxxxx> for the patch 02/12.
- Add the changes requested by Marc Zyngier for the 3/12 patch.
- Remove the patch 11/12 (a consequence of a discussion between Jiaxun Yang
and Marc Zyngier.
- Re-base onto the master branch, with no functionality impact.
v2:
- Apply correct Signed-off-by to avoid confusion.
