Compare with v9 there are only some small changes: 1. Squash patch 2/50 and 3/50 in v9 together, never check host include/linux/bpf.h, so bpf feature check will always green. 2. Fix compiling error when CONFIG_BPF_SYSCALL is set but CONFIG_BPF_EVENT is unset. See patch 1/50. 3. In add_perf_probe_events(), always init kernel symbol maps.
