There isn't. IIRC, back when I finalized the PWM subsystem during the last
cycle, Arnd Bergmann suggested that I request an account and repository on
kernel.org back when the subsystem was ready. At the time I didn't think
it necessary, but reading this, perhaps it wouldn't be such a bad idea.
kernel.org should have better availability than gitorious.
