Merge branch 'bpf_probe_read_user'

Daniel Borkmann says:

====================
This set adds probe_read_{user,kernel}(), probe_read_str_{user,kernel}()
helpers, fixes probe_write_user() helper and selftests. For details please
see individual patches.

Thanks!

v2 -> v3:
  - noticed two more things that are fixed in here:
   - bpf uapi helper description used 'int size' for *_str helpers, now u32
   - we need TASK_SIZE_MAX + guard page on x86-64 in patch 2 otherwise
     we'll trigger the 00c42373d397 warn as well, so full range covered now
v1 -> v2:
  - standardize unsafe_ptr terminology in uapi header comment (Andrii)
  - probe_read_{user,kernel}[_str] naming scheme (Andrii)
  - use global data in last test case, remove relaxed_maps (Andrii)
  - add strict non-pagefault kernel read funcs to avoid warning in
    kernel probe read helpers (Alexei)
