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. 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.
