Subject: [PATCH -fixes 0/2] svnapot fixes

While merging riscv napot and arm64 contpte support, I noticed we did
not abide by the specification which states that we should clear a
napot mapping before setting a new one, called "break before make" in
arm64 (patch 1). And also that we did not add the new hugetlb page size
added by napot in hugetlb_mask_last_page() (patch 2).

Alexandre Ghiti (2):
  riscv: Fix set_huge_pte_at() for NAPOT mapping
  riscv: Fix hugetlb_mask_last_page() when NAPOT is enabled
