[PATCH] define for_each_online_pgdat
This patch defines for_each_online_pgdat() as a replacement of
for_each_pgdat()
Now, online nodes are managed by node_online_map. But for_each_pgdat()
uses pgdat_link to iterate over all nodes(pgdat). This means management
structure for online pgdat is duplicated.
I think using node_online_map for for_each_pgdat() is simple and sane
rather ather than pgdat_link. New macro is named as
for_each_online_pgdat(). Following patch will fix callers of
for_each_pgdat().
The bootmem allocater uses for_each_pgdat() before pgdat initialization. I
don't think it's sane. Following patch will fix it.
