Yes we are always touching architecture code. For that part, we'll
still submit our patches to linux-mips tree. But we're also maintaining
many platform code under /arch/mips/loongson64 and also platform
drivers such as hwmon, cpufreq and YeeLoong Laptop driver I'm trying to
submit recently. For that part, make a pull request might be more
efficient than apply patches to linux-mips for many times. Just as what
arm architecture did.

We would like to reduce Ralf's work load. Not bypassing him.

I agree with that. Ralf really need help.
