Ahh.. Right.. I guess I should have remembered you were working on those
changes (even though I don't think I saw the final results sent to lkml
or anything).

Sorry about that.

So I've cherry picked the two changes from the ppc tree, applied them
onto linus' git tree and then rebased my changes ontop of them.

The net of the change to the patch set:

Added to the head of the patch queue:
powerpc: Rework VDSO gettimeofday to prevent time going backwards
powerpc: Clean up obsolete code relating to decrementer and timebase

Modified to resolve collision:
powerpc: Simplify update_vsyscall

Dropped (as earlier patches already made equivalent changes):
powerpc: Cleanup xtime usage

The full set is in the attached tarball.

Thomas, would you consider re-adding these? Hopefully that will avoid
any -next collisions.

thanks
