I think BPF JIT for seccomp on ARM recently got applied to -mm tree

Thanks for the pointer.
For the ARM part, looks like Nicolas's patch requires to implement two
wrappers for each arch:
void seccomp_jit_compile(struct seccomp_filter *fp);
void seccomp_jit_free(struct seccomp_filter *fp);
The implementation of these wrappers is almost identical to:
void bpf_jit_compile(struct sk_filter *fp);
void bpf_jit_free(struct sk_filter *fp);
While this patch uses a unified interface for both packet & seccomp filters.
bpf_func_t bpf_jit_compile(struct sock_filter *filter, unsigned int flen);
void bpf_jit_free(bpf_func_t bpf_func);
A unified interface seems more clean, imho.
Shouldn't be hard to merge though.
