Thanks for this series, I reviewed it and tested it on my platform, so
you can add for all the patches:

Reviewed-by: Gregory CLEMENT <gregory.clement@...tlin.com>
Tested-by: Gregory CLEMENT <gregory.clement@...tlin.com>

However I add to fix the patch " MIPS: Handle mips_cps_core_entry within
lower 4G", I think you missed a case. I will comment on it.

Gregory
