Merge branch 'move-ld_abs-to-native-BPF'
Daniel Borkmann says:
====================
This set simplifies BPF JITs significantly by moving ld_abs/ld_ind
to native BPF, for details see individual patches. Main rationale
is in patch 'implement ld_abs/ld_ind in native bpf'. Thanks!
v1 -> v2:
- Added missing seen_lds_abs in LDX_MSH and use X = A
initially due to being preserved on func call.
- Added a large batch of cBPF tests into test_bpf.
- Added x32 removal of LD_ABS/LD_IND, so all JITs are
covered.
====================
