Patches:
1. Fix bpf prologue generation. bpf_probe_read is unavailable for arch
   with overlapping address space.  If uaccess, use bpf_probe_read_user.
   Otherwise, use bpf_probe_read_kernel.
2. Fix uaccess in kprobes. Now perf probe add with @user attribute works

v1->v2:
- Split the patches and add Acked-By

Thank you.
