Loongson told me this problem before.

Debian won't accept a patch that is not not upstreamed.
Even your patch is upstreamed, we also need have some talk
whether to set is as default.

We are using 3A 1000 as Debian build daemon, they are buggy,
while is not very unstable.
And I am using an 3A 3000 as my laptop, it is some less stable than 1000,
while acceptable.
