Alexandre Ghiti c962a6e746 riscv: Improve flush_tlb_range() for hugetlb pages ... flush_tlb_range() uses a fixed stride of PAGE_SIZE and in its current form, when a hugetlb mapping needs to be flushed, flush_tlb_range() flushes the whole tlb: so set a stride of the size of the hugetlb mapping in order to only flush the hugetlb mapping. However, if the hugepage is a NAPOT region, all PTEs that constitute this mapping must be invalidated, so the stride size must actually be the size of the PTE. Note that THPs are directly handled by flush_pmd_tlb_range().
