Can this even happen? We have either pgtable-2level.h or
pgtable-3level.h, both of which define PTE_HWTABLE_PTRS.

I guess not for arm. But I'm not sure for other ARCHs.

Oh it's a generic include. Sorry for the confusion.

All good then!

This code is 2+ years old.  Do we think it warrants a cc:stable?

Not needed - ARM only gained Kasan support this cycle, and this patch
does not affect any other architectures
