Message

This series brings transparent huge pages to RISCV on 64-bit.

I have tested these testcases of vm selftest under qemu-riscv64:
khugepaged
split_huge_page_test
transhuge-stress

Nanyong Sun (4):
  riscv: mm: add _PAGE_LEAF macro
  riscv: mm: make pmd_bad() check leaf condition
  riscv: mm: add param stride for __sbi_tlb_flush_range
  riscv: mm: add THP support on 64-bit

Thanks.  These were too late for the current merge window.  We still 
have some stuff in flight, I'll take a look after things calm down a 
bit.
