[PATCH bpf-next v4 0/2] powerpc64/bpf: Inline helper in powerpc JIT

[Saket Kumar Bhaskar]

This series add support for internal only per-CPU instructions,
inlines the bpf_get_smp_processor_id() and bpf_get_current_task()
helper calls for powerpc BPF JIT.

Changes since v3:
* Added break after computing per cpu address so that the computed 
  address is not overwritten by src_reg as suggested by AI bot.

v3: https://lore.kernel.org/all/cover.1764930425.git.skb99@xxxxxxxxxxxxx/

Changes since v2:
* Collected Reviewed-by tag.
* Inlined bpf_get_current_task/btf().
* Fixed addressing of src_reg and BPF_REG_0. (Christophe) 
* Fixed condition for non smp case as suggested by Christophe.

v2: https://lore.kernel.org/all/cover.1762422548.git.skb99@xxxxxxxxxxxxx/

Changes since v1:
* Addressed Christophe's comments.
* Inlined bpf_get_current_task() as well.

v1: https://lore.kernel.org/all/20250311160955.825647-1-skb99@xxxxxxxxxxxxx/
