I assume that the user knows that they are using a RISC-V machine. On the other hand, seeing a "SMP:" prefix for a message indicates the provenance of the message. I honestly don't see the point in this change. M. -- Without deviation from the norm, progress is not possible.

The intention was to distinguish arch specific prints from generic kernel prints at boot-time because "SMP: " prefix was not making it obvious that these are arch specific prints. I am certainly fine dropping this patch as well. Regards, Anup > > M. > > -- > Without deviation from the norm, progress is not possible.
