I have patches 1-6 applied locally - would you be happy for those to be
pushed to mips-next without 7-10? I know ip27_defconfig still builds but
have no idea whether it still works :)
I don't appear to have received patches 7 or 9 but I see from archives
there'll be a v3 of patch 9 at least.
So I can either apply 1-6 for v5.1 or defer the whole series. Let me
know - I'm happy either way.
Thanks,
Paul
