Thanks for performing the tests of the patchset. I really appreciate this.
Regarding the problems you got. You must be doing something wrong, since
Matt Redfearn already did the tests on Loongson3:
https://lkml.org/lkml/2018/1/22/610
and the kernel turns out to be booting without troubles.

So could you make sure, that you did everything right? Particularly, you
said the patch (singular) isn't working. But this patch functionality depends
on the whole patchset. Did you apply all the patches I sent and fully rebuild
the kernel then?

Regards,
-Sergey
