I have patches to remove the blackfin, cris, frv, m32r, metag, mn10300,
score, tile and unicore32 architectures from the kernel, these should be
part of linux-next in the next few days. It's not a big issue, but if you keep
patching them, this will cause a merge conflict.
It might be easier to drop them from your patch as well.

I have patches to remove the blackfin, cris, frv, m32r, metag, mn10300,
score, tile and unicore32 architectures from the kernel, these should be
part of linux-next in the next few days. It's not a big issue, but if you keep
patching them, this will cause a merge conflict.
It might be easier to drop them from your patch as well.
