The other issue I'm running into is: CC mm/huge_memory.o mm/huge_memory.c: In function =E2=80=98do_huge_pmd_prot_none=E2=80=99: mm/huge_memory.c:789:3: error: incompatible type for argument 3 of =E2=80= =98update_mmu_cache=E2=80=99 In file included from include/linux/mm.h:44:0, from mm/huge_memory.c:8: /home/ralf/src/linux/linux-mips/arch/mips/include/asm/pgtable.h:375:91:= note: expected =E2=80=98struct pte_t *=E2=80=99 but argument is of typ= e =E2=80=98pmd_t=E2=80=99 mm/huge_memory.c: In function =E2=80=98__split_huge_page_map=E2=80=99: mm/huge_memory.c:1424:2: error: implicit declaration of function =E2=80= =98pmd_pgprot=E2=80=99 [-Werror=3Dimplicit-function-declaration] mm/huge_memory.c:1424:7: error: incompatible types when assigning to ty= pe =E2=80=98pgprot_t=E2=80=99 from type =E2=80=98int=E2=80=99 cc1: some warnings being treated as errors make[1]: *** [mm/huge_memory.o] Error 1 which is caused by: commit a573b4dfcf58f86235d586ea1f82ed54b2b7e620 Author: Peter Zijlstra Date: Tue Jul 17 18:25:14 2012 +0200 mm/mpol: Create special PROT_NONE infrastructure is adding a update_mmu_cache() call with incorrect arguments to do_huge_pmd_prot_none(). This only shows up where update_mmu_cache() is implemented as a C function; the usual macro implementation is eatin= g everything and the kitchensink as arguments. Ralf
