Subject: [PATCH] NOMMU: move the fallback arch_vma_name() to a sensible place
X-Git-Tag: MMI-PSA29.97-13-9~47314
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f269fdd1829acc5e53bf57b145003e5733133f2b;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

[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.
