Thanks both for taking a look.

The main benefit of merging in 6.3 would be to make Raghavendra's life
simpler/easier so he can build the next version of his arm64 TLBI
series on top. But I guess he can still do that with a topic branch.

I'll go ahead and send a v2 on top of the changes from Hou you queued
for 6.3, Sean, and we can plan on landing that in 6.4 (barring any
further feedback or conflicts).
