Subject: [PATCH v2 bpf 00/11] bpf: random unpopular userspace fixes (32 bit et al)

This mostly issues the cross build (1) errors for 32 bit (2)
MIPS (3) with minimal configuration (4) on Musl (5). The majority
of them aren't yesterday's, so it is a "who does need it outside
of x86_64 or ARM64?" moment again.
Trivial stuff in general, not counting the first three (they are
50/50).

From v1[0]:
 - use *___local struct definitions for BPF programs instead of
   BTF_TYPE_EMIT() and ifdef-play (Andrii);
 - cast uin64_t to unsigned long long to *really* fix the format
   literal warnings (Song, David, Andrii);
 - collect Acked-bys for the rest (Maciej, Kumar, Song);
 - adjust the subjects to match their usual look (Andrii);
 - expand the commit messages a bit for 0008
   (-Wshift-count-overflow) and 0010 (-Wsequence-point) a bit to
   mention they actually mitigate the third-party issues (Andrii);
 - rebase and send to bpf instead of bpf-next (hope the first three
   are okay for it).
