[PATCH] ARM: Wire up bpf syscall

[PATCH] ARM: Wire up bpf syscall

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Add the bpf syscall to ARM.

Signed-off-by: Thierry Reding <treding@nvidia.com>
---
Note that I haven't tested whether this new syscall actually works on ARM,
but it certainly gets rid of the annoying "syscall bpf not implemented"
warning.

I guess you're using an old kernel... the commit adding this is already
merged - v3.18-rc3~4^2~4

Indeed, I had just realized that I had been working on a branch with an
out-dated base and was going to ask you to disregard this patch.

Sorry for the noise,
