Helping out with arch/riscv maintenance

[Paul Walmsley]

Hi folks,

At Palmer's request, I'll be helping out with arch/riscv maintenance for a 
little while.  Palmer's been doing a great job, and I'm sure I won't be 
able to do as good of a job as he's been doing.  Let's see if we can keep 
things moving smartly in the interim.

As you may have seen, a fixes PR was just sent to Linus.  Many of the 
patches were initially collected by Alex Ghiti, and I borrowed some of his 
curation work for that branch - thanks very much, Alex.  Will plan to send 
at least one more set of fixes to Linus before the merge window.

Some of my local kernel maintenance infrastructure is a bit out of date.  
I'll be cleaning that up over the next few weeks.  Thanks for your 
patience while that gets updated.


- Paul
