[PATCH bpf-next v2 0/3] add batched ops support for percpu

[Pedro Tammela <pctammela@gmail.com>]

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

It also introduces a standard way to define per-cpu values via the
'BPF_PERCPU_TYPE()' macro, which handles the alignment transparently.
This was already implemented in the selftests and was merely refactored
out to libbpf, with some simplifications for reuse.

The tests were updated to reflect all the new changes.

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

Pedro Tammela (3):
  bpf: add batched ops support for percpu array
  libbpf: selftests: refactor 'BPF_PERCPU_TYPE()' and 'bpf_percpu()'
    macros
  bpf: selftests: update array map tests for per-cpu batched ops
