My suggestion, although I didn't looked too much on it:
Apply it to v4.9 and higher only.
I think I started fixing trace functionality on parisc around 4.6,
which is probably why applying it fails on v4.4 and v3.x

The problem is, if you backport the generic patches, it will completely
break any arch that isn't updated. This also includes the archs that
are no longer supported upstream, as they were not changed to handle
the generic updates either.

Does this mean that someone (Steve) will send a backport of this to all
relevant stable trees? Right now it looks like the series will randomly
apply on a mix of trees, which can't be good.
