Subject: [PATCH bpf-next v4 0/3] add batched ops for percpu array

This patchset introduces batched operations for the per-cpu variant of
the array map.

It also removes the percpu macros from 'bpf_util.h'. This change was
suggested by Andrii in a earlier iteration of this patchset.

The tests were updated to reflect all the new changes.

v3 -> v4:
- Prefer 'calloc()' over 'malloc()' on batch ops tests
- Add missing static keyword in a couple of test functions
- 'offset' to 'cpu_offset' as suggested by Martin

v2 -> v3:
- Remove percpu macros as suggested by Andrii
- Update tests that used the per cpu macros

v1 -> v2:
- Amended a more descriptive commit message

Pedro Tammela (3):
  bpf: add batched ops support for percpu array
  bpf: selftests: remove percpu macros from bpf_util.h
  bpf: selftests: update array map tests for per-cpu batched ops
