[PATCH] of: Print rather than WARN'ing when overlap check fails

__rmem_check_for_overlap() is called very early in boot, and on some powerpc systems it's not safe to call WARN that early in boot. If the overlap check fails the system will oops instead of printing a warning. Furthermore because it's so early in boot the console is not up and the user doesn't se

[PATCH v2] platforms/powernv: Add support for Nvlink NPUs

NV-Link is a high speed interconnect that is used in conjunction with a PCI-E connection to create an interface between CPU and GPU that provides very high data bandwidth. A PCI-E connection to a GPU is used as the control path to initiate and report status of large data transfers sent via the NV-L
