It is a direct replacement of the patch 3 in discussion [1]

map_local_storage_charge, map_local_storage_uncharge,
and map_owner_storage_ptr.
It is only compiler tested to demo the idea.

The variable np in function m10v_smp_init takes the return value
of of_find_compatible_node, which gets a node but does not put it. If
this node is not put it may cause a memory leak. Hence put np after its
life has been exhausted.

This patch enables memcg-based memory accounting for memory allocated
by __bpf_map_area_alloc(), which is used by most map types for
large allocations.
Following patches in the series will refine the accounting for
some map types.

Currently bpf is using the memlock rlimit for the memory accounting.
This approach has its downsides and over time has created a significant
amount of problems:
1) The limit is per-user, but because most bpf operations are performed
as root, the limit has a little value.
2) It's hard to come u
