This patch series introduces support for the PROBE_MEM32,
bpf_addr_space_cast and PROBE_ATOMIC instructions in the powerpc BPF JIT,
facilitating the implementation of BPF arena and arena atomics.

All selftests related to bpf_arena, bpf_arena_atomic(except
load_acquire/store_release) enablement are passing:
