Merge branch 'restrict-bpf_probe_read'
 
Daniel Borkmann says:

====================
Small set of fixes in order to restrict BPF helpers for tracing which are
broken on archs with overlapping address ranges as per discussion in [0].
I've targetted this for -bpf tree so they can be routed as fixes. Thanks!

v1 -> v2:
  - switch to reusable %pks, %pus format specifiers (Yonghong)
    - fixate %s on kernel_ds probing for archs with overlapping addr space
