You're right. I had a stale tree registered as "origin" and didn't realize it 
:). I've rebased the patches on top of upstream/master now (which was conflict 
free) keeping the "linux-user .mak" patch from you in. I also fixed a few TCGv 
i32/64/ptr hickups that were still left in the tree.

Considering the minimal amount of changes this incurred, I will refrain from 
reposting a giant 60-patches patch set and instead just pushed it to a new 
branch on github:

  git://github.com/agraf/qemu.git aarch64-tcg-batch1-v2
