We have yet to encounter such a case. It's not currently possible on
power (some old embedded chips could do 1K and 2K page sizes in the TLB
iirc but we never supported that in Linux and it's being phased out in
HW).
I suggest that gets dealt with when/if it needs to, which means probably
never :-)
Cheers,
Ben.
