[PATCH] NOMMU: move the fallback arch_vma_name() to a sensible place
Move the fallback arch_vma_name() to a sensible place (kernel/signal.c).
Currently it's in fs/proc/task_mmu.c, a file that is dependent on both
CONFIG_PROC_FS and CONFIG_MMU being enabled, but it's used from
kernel/signal.c from where it is called unconditionally.
