Ok, I fixed it as per below. Does everyone agree?
Thanks,

----------------> From 6e683978132907ff339e8a01a4d901c75709e62c Mon Sep 17 00:00:00 2001 From: Ingo Molnar <mingo@kernel.org> Date: Sat, 20 Oct 2012 00:33:01 +0200 Subject: [PATCH] MIPS/thp: Fix update_mmu_cache() cache call
As per recent upstream commit:
b113da65785d mm: Add and use update_mmu_cache_pmd() in transparent huge page code.
The call in do_huge_pmd_prot_none() needs to call update_mmu_cache_pmd() as well.
This resolves a MIPS build error triggered on linux-next.
