Merge branch 'bpf-require-an-owned-cpumask-for-bpf_cpumask_populate'

Nicholas Dudar says:

====================
bpf: require an owned cpumask for bpf_cpumask_populate()

bpf_cpumask_populate() writes its destination with bitmap_copy() but
types it as struct cpumask *, so the verifier accepts a borrowed,
read-only cpumask (for example from scx_bpf_get_online_cpumask()) as a
writable destination. Fix it and add a selftest for coverage.

Changelog:
----------
v2 -> v3 (v1/v2 were a private report to security@kernel.org)

 * Split the fix and selftest into separate patches.
 * Target bpf-next instead of bpf.
====================
