6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Natanael Copa <ncopa@xxxxxxxxxxxxxxx>
commit 62248b22d01e96a4d669cde0d7005bd51ebf9e76 upstream.
Include the header that defines u32.
This fixes build of 6.6.23 and 6.1.83 kernels for Alpine Linux, which
uses musl libc. I assume that GNU libc indirecly pulls in linux/types.h.
Fixes: 9707ac4fe2f5 ("tools/resolve_btfids: Refactor set sorting with types from btf_ids.h")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218647
