True. I should have included all interested parties in the recipients of 
the cover letter. My bad.

I offered to write a patch to add a clocksource to replace the 
arch_gettimeoffset functionality for RPC and EBSA110.

You even replied to that offer.

I did not propose degrading functionality while there is someone able to 
test modernization patches (assuming there is...).

Would you consider merging untested modernization patches for the 
arch_gettimeoffset API?

Sorry for any frustration I've caused you.

The thread went way off-topic when Christoph took the opportunity to 
suggest the removal of RPC and EBSA110. That doesn't interest me.

My interest remains API modernization. The actual patches I've sent are 
intended to modernize the clock API *without* degrading any functionality.

OK. I'll have to improve my patch submission scripts.
