[PATCH net-next v19 08/14] mm: page_frag: use __alloc_pages() to replace alloc_pages_node()

[Yunsheng Lin <yunshenglin0825@gmail.com>]

It seems there is about 24Bytes binary size increase for
__page_frag_cache_refill() after refactoring in arm64 system
with 64K PAGE_SIZE. By doing the gdb disassembling, It seems
we can have more than 100Bytes decrease for the binary size
by using __alloc_pages() to replace alloc_pages_node(), as
there seems to be some unnecessary checking for nid being
NUMA_NO_NODE, especially when page_frag is part of the mm
system.
