The other issue I'm running into is:
CC mm/huge_memory.o
mm/huge_memory.c: In function ‘do_huge_pmd_prot_none’:
mm/huge_memory.c:789:3: error: incompatible type for argument 3 of ‘update_mmu_cache’
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 ‘struct pte_t *’ but argument is of type ‘pmd_t’
mm/huge_memory.c: In function ‘__split_huge_page_map’:
mm/huge_memory.c:1424:2: error: implicit declaration of function ‘pmd_pgprot’ [-Werror=implicit-function-declaration]
mm/huge_memory.c:1424:7: error: incompatible types when assigning to type ‘pgprot_t’ from type ‘int’
cc1: some warnings being treated as errors
make[1]: *** [mm/huge_memory.o] Error 1
which is caused by:
commit a573b4dfcf58f86235d586ea1f82ed54b2b7e620
Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
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 eating
everything and the kitchensink as arguments.
