On 32-bit architecture, roundup_pow_of_two() can return 0 when the argument has upper most bit set due to resulting 1UL << 32. Add a check for this case. Fixes: d5a3b1f ("bpf: introduce BPF_MAP_TYPE_STACK_TRACE") Signed-off-by: Bui Quang Minh <minhquangbui99@gmail.com>

Use helper bpf_redirect_map() and bpf_redirect_map_multi() to test bpf
arg ARG_CONST_MAP_PTR and ARG_CONST_MAP_PTR_OR_NULL. Make sure the
map arg could be verified correctly when it is NULL or valid map
pointer.
Add devmap and devmap_hash in struct bpf_test due to bpf_redirect_{map,
map_multi} limit.
Test result:

Use helper bpf_redirect_map() and bpf_redirect_map_multi() to test bpf
arg ARG_CONST_MAP_PTR and ARG_CONST_MAP_PTR_OR_NULL. Make sure the
map arg could be verified correctly when it is NULL or valid map
pointer.
Add devmap and devmap_hash in struct bpf_test due to bpf_redirect_{map,
map_multi} limit.

The driver would disable the worker when cpu is being put offline, but it happens closer to the end of cpufreq_offline(). The function qcom_lmh_dcvs_poll() can be running in parallel with this, when policy->cpus already has been updated. Read policy->related_cpus instead.
