It doesn't look to bad to me (however it is a bit late in the cycle :-(
).  Once you are happy, just put it in your tree (some of the conflicts
are against the current -rc3 based version of your tree anyway) and I
will cope with it on Monday.

You could do a test merge against next-<date>^^ (that leaves out
Andrew's patch series) and if you think there is anything tricky please
send me a "git diff-tree --cc HEAD" after you have resolved the
conflicts to your satisfaction and committed the test merge or just
point me at the test merge in a tree somewhere (like this one).
