The first three patches of this series are ARM specific and have nothing
to do with the queued core/entry changes in tip. They are independent of
each other and these three ARM64 changes have no business in my tree.

If the ARM64 folks want to apply the rest of your series then they have
to pull the core/entry branch into their for-next/core branch first so
the whole thing builds.

But given that the merge window opens on sunday, this is probably moot
anyway and the rest of this series can go on top of rc1 in the ARM64
tree w/o any further complications.
