Jerome Marchand 74b2f8e009 docs: bpf: map_array: Specify BPF_MAP_TYPE_PERCPU_ARRAY value size limit 
JIRA: https://issues.redhat.com/browse/RHEL-139985

commit 44bf4611827b7477db188ec932b827e1fabd3ee1
Author: Alex Tran <alex.t.tran@gmail.com>
Date:   Fri Nov 14 22:35:31 2025 -0800

    docs: bpf: map_array: Specify BPF_MAP_TYPE_PERCPU_ARRAY value size limit

    Specify value size limit for BPF_MAP_TYPE_PERCPU_ARRAY which
    is PCPU_MIN_UNIT_SIZE (32 kb). In percpu allocator (mm: percpu),
    any request with a size greater than PCPU_MIN_UNIT_SIZE is rejected.
