Yasunori Goto f2d0aa5bf8 [PATCH] memory hotplug: __GFP_NOWARN is better for __kmalloc_section_memmap() 
Add __GFP_NOWARN flag to calling of __alloc_pages() in
__kmalloc_section_memmap().  It can reduce noisy failure message.

In ia64, section size is 1 GB, this means that order 8 pages are necessary
for each section's memmap.  It is often very hard requirement under heavy
memory pressure as you know.  So, __alloc_pages() gives up allocation and
shows many noisy stack traces which means no page for each sections.
(Current my environment shows 32 times of stack trace....)

But, __kmalloc_section_memmap() calls vmalloc() after failure of it, and it
can succeed allocation of memmap.  So, its stack trace warning becomes just
noisy.  I suppose it shouldn't be shown.
