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.
The last patch in the series has fix for arena spinlock selftest
failure.
This series is rebased on top of:
https://lore.kernel.org/bpf/20250717202935.29018-2-puranjay@kernel.org/
All selftests related to bpf_arena, bpf_arena_atomic(except
load_acquire/store_release) enablement are passing:

Though, there is else condition which is envoked incase llvm doesn't have support for may_goto insn, which we are looking into. Since llvm-20 has support for may_goto, we are not seeing this failure there(the selftest passes). So we are planning to fix this in separate patch for llvm-19 for now.
