Palmer, with Konstantin's help, recently set up a shared tree for
arch/riscv patches at:
git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git
As with other kernel.org git trees, it can be browsed via HTTPS at:
https://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git/
This tree is what we'll use for upstream-bound patches going forward.
