Merge patch "riscv: Fix compilation error with FAST_GUP and rv32"

I'm picking this up on top of the broken patch for the merge window, as
the offending patch breaks the rv32 build and was itself a fix so isn't
on for-next.

* b4-shazam-merge:
  riscv: Fix compilation error with FAST_GUP and rv32
  riscv: Fix pte_leaf_size() for NAPOT
  Revert "riscv: mm: support Svnapot in huge vmap"
