Subject: [PATCH 0/4] xfrm: Add support for RFC 9611 per cpu xfrm states

This patchset implements the xfrm part of per cpu SAs as specified in
RFC 9611.

Patch 1 adds the cpu as a lookup key and config option to to generate
acquire messages for each cpu.

Patch 2 caches outbound states at the policy.

Patch 3 caches inbound states on a new percpu state cache.

Patch 4 restricts percpu SA attributes to specific netlink message types.

Please review and test.

Changes from v1:

- Add compat layer attributes

- Fix a 'use always slowpath' condition

- Fix forgotten update of xfrm_expire_msgsize()
