memoryless nodes: fixup uses of node_online_map in generic code
Here's a cut at fixing up uses of the online node map in generic code.
mm/shmem.c:shmem_parse_mpol()
Ensure nodelist is subset of nodes with memory.
Use node_states[N_HIGH_MEMORY] as default for missing
nodelist for interleave policy.
mm/shmem.c:shmem_fill_super()
initialize policy_nodes to node_states[N_HIGH_MEMORY]
mm/page-writeback.c:highmem_dirtyable_memory()
sum over nodes with memory
mm/page_alloc.c:zlc_setup()
allowednodes - use nodes with memory.
mm/page_alloc.c:default_zonelist_order()
average over nodes with memory.
mm/page_alloc.c:find_next_best_node()
skip nodes w/o memory.
N_HIGH_MEMORY state mask may not be initialized at this time,
unless we want to depend on early_calculate_totalpages() [see
below]. Will ZONE_MOVABLE ever be configurable?
mm/page_alloc.c:find_zone_movable_pfns_for_nodes()
spread kernelcore over nodes with memory.
This required calling early_calculate_totalpages()
unconditionally, and populating N_HIGH_MEMORY node
state therein from nodes in the early_node_map[].
If we can depend on this, we can eliminate the
population of N_HIGH_MEMORY mask from __build_all_zonelists()
and use the N_HIGH_MEMORY mask in find_next_best_node().
mm/mempolicy.c:mpol_check_policy()
Ensure nodes specified for policy are subset of
nodes with memory.
