Yes, I read that policy. and per policy, I waited for a week and pinged.

What other patches you were asking? LLVM HW EH Part-2 change or including Local Unwind?  
I did at first put the whole design and implementation in RFC, but I was asked to separate Local Unwind and HW exception.
So I did and submitted a patch specific for HW exception, but was asked to further divide it.
So I did, and this is part-1 for Clang.  After this patch is landed, yes I will work on next patch.

Meanwhile please refer to those RFC threads and Code/Wiki in https://github.com/tentzen/llvm-project for more details.

One step at a time, for now for this patch, is there any other feedback? thanks.
