*	bpf, ppc64: remove ld_abs/ld_ind	Daniel Borkmann	2018-05-04	1	-180/+0
\| \| \| \| \| \| \| \| \| \| \| \|	Since LD_ABS/LD_IND instructions are now removed from the core and reimplemented through a combination of inlined BPF instructions and a slow-path helper, we can get rid of the complexity from ppc64 JIT.

*	powerpc/ebpf/jit: Implement JIT compiler for extended BPF	Naveen N. Rao	2016-06-24	1	-0/+180
	PPC64 eBPF JIT compiler. Enable with: echo 1 > /proc/sys/net/core/bpf_jit_enable or echo 2 > /proc/sys/net/core/bpf_jit_enable ... to see the generated JIT code. This can further be processed with tools/net/bpf_jit_disasm. With CONFIG_TEST_BPF=m and 'modprobe test_bpf': test_bpf: Summary: 305 PASSED, 0 FAILED, [297/297 JIT'ed] ... on both ppc64 BE and LE. The details of the approach are documented through various comments in the code. Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Naveen N.
