For patch #5, correct myself, enable is verb, usable is adjective,
so just keep it as is, or modify the log as following:
---
selftests/bpf: Enable CAN_USE_LOAD_ACQ_STORE_REL for LoongArch
In order to do the following load-acquire and store-release tests
on LoongArch:
sudo ./test_progs -t verifier_load_acquire
sudo ./test_progs -t verifier_store_release
sudo ./test_progs -t verifier_precision/bpf_load_acquire
sudo ./test_progs -t verifier_precision/bpf_store_release
sudo ./test_progs -t compute_live_registers/atomic_load_acq_store_rel
it needs to enable CAN_USE_LOAD_ACQ_STORE_REL for LoongArch.
---
For short, replace "make ... usable" with "enable ...".
Thanks,
Tiezhu
