[PATCH bpf-next v1 0/3] Improve .BTF_ids patching and alignment

[Tony Ambardar <tony.ambardar@gmail.com>]

Hello all,

This patch series offers improvements to the way .BTF_ids section data is
created and later patched by resolve_btfids.

Patch #1 simplifies the byte-order translation in resolve_btfids while
making it more resilient to future .BTF_ids encoding updates.

Patch #2 makes sure all BTF ID data is 4-byte aligned, and not only the
.BTF_ids used for vmlinux.

Patch #3 syncs the above changes in btf_ids.h to tools/include, obviating
a previous alignment fix in selftests/bpf.

Feedback and suggestions are welcome!

Best regards,
Tony
