Dupe of https://patchwork.kernel.org/patch/10032875/

   Sorry!
   Not an exact dupe, though -- mine has clock/power #define's used,
yours -- only bare #s. :-)

   Hmm... what's the fate of this series?

There is now a v2 of Geert's series which incorporates your enhancements.

   I suggested to respin it. :-)

Thanks, that would have been my suggestion too :)

I will apply that.

   Thank you.
   For the record, I had better luck than Geert testing SMP on Eagle:
   only CPU0 couldn't be offlined (and I was unable to find a
   workaround), others could be on/ offlined w/o issues. As for
   suspend/resume -- it did work but I could only test s2idle
   (/sys/power/mem_sleep had no other variants)...

Thanks. Perhaps you have a more recent firmware than Geert.
I would expect the CPU0 issue you describe will be resolved in time in
the firmware.
