For both patches I get:
Commit: 0146c955ff59 ("riscv: Fix huge_ptep_set_wrprotect when PTE is a NAPOT")
	Fixes tag: Fixes: f2aeb0118ddd ("riscv: mm: support Svnapot in hugetlb page")
	Has these problem(s):
		- Target SHA1 does not exist

This particular one is 82a1a1f3bfb6 in riscv/for-next.

Cheers,
Conor.
