Nope,
These were added in tip, which I rebased on to in order to post this late, but didn't have
the time to retest the ~100 other patches (mostly MPAM driver) that sit on top of this.
x86 was quite happy without these. (There are too many moving parts!)

- thanks for catching these.


Thanks,

James
