H A D | mmu_context.h | diff 62e88b1c00de9cb30d937841ed5debed871070b8 Tue Nov 18 19:23:50 CET 2014 Dave Hansen <dave.hansen@linux.intel.com> mm: Make arch_unmap()/bprm_mm_init() available to all architectures
The x86 MPX patch set calls arch_unmap() and arch_bprm_mm_init() from fs/exec.c, so we need at least a stub for them in all architectures. They are only called under an #ifdef for CONFIG_MMU=y, so we can at least restict this to architectures with MMU support.
blackfin/c6x have no MMU support, so do not call arch_unmap(). They also do not include mm_hooks.h or mmu_context.h at all and do not need to be touched.
s390, um and unicore32 do not use asm-generic/mm_hooks.h, so got their own arch_unmap() versions. (I also moved um's arch_dup_mmap() to be closer to the other mm_hooks.h functions).
xtensa only includes mm_hooks when MMU=y, which should be fine since arch_unmap() is called only from MMU=y code.
For the rest, we use the stub copies of these functions in asm-generic/mm_hook.h.
I cross compiled defconfigs for cris (to check NOMMU) and s390 to make sure that this works. I also checked a 64-bit build of UML and all my normal x86 builds including PARAVIRT on and off.
