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

[Alexander Lobakin <alobakin@xxxxx>]

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).
