I'm trying to unwind all the patches going around, Linus' feedback and
so on, and figure out what this means in concrete terms especially in
the light of the 3.15 merge window coming up.

I tried to apply your patchset "[PATCH v2 0/2] x86: Relocate the compat
vdso per process" on top of tip:x86/vdso, but it conflicts pretty hard
-- I guess you are using a different baseline, but that makes it
complicated to deal with.

Otherwise, it seems the logical way forward.  Could you and/or Stefani
work out the conflicts between the patchsets?

In the meantime I'm going to apply Stefani's first patch.
