mm/page_alloc.c: remove meaningless VM_BUG_ON() in pindex_to_order()
Patch series "Cleanups and fixup for page_alloc", v2.
This series contains cleanups to remove meaningless VM_BUG_ON(), use
helpers to simplify the code and remove obsolete comment. Also we avoid
allocating highmem pages via alloc_pages_exact[_nid]. More details can be
found in the respective changelogs.
This patch (of 5):
It's meaningless to VM_BUG_ON() order != pageblock_order just after
setting order to pageblock_order. Remove it.
