Hi Atish,

This series adds the counter delegation extension support. It is based on
very early PoC work done by Kevin Xue and mostly rewritten after that.
The counter delegation ISA extension(Smcdeleg/Ssccfg) actually depends
on multiple ISA extensions.
So as you've probably seen, I've started adding some of the prerequisite 
ISA support patches from your series to the RISC-V for-next branch.  
Looks like you're planning to repost the series at least one more time; 
you can either include those patches again, or base it on RISC-V for-next 
as you wish, but if you include those patches again, please note in your 
cover letter if you've changed anything.


thanks,

- Paul
