calculate_numa_remap_pages() is called only by __init initmem_init()
further calculate_numa_remap_pages is calling:
__init find_e820_area() and __init reserve_early()
So calculate_numa_remap_pages() should be __init calculate_numa_remap_pages().
WARNING: arch/x86/built-in.o(.text+0x82ea3): Section mismatch in reference from the function calculate_numa_remap_pages() to the function .init.text:find_e820_area()
The function calculate_numa_remap_pages() references
the function __init find_e820_area().
This is often because calculate_numa_remap_pages lacks a __init
annotation or the annotation of find_e820_area is wrong.
WARNING: arch/x86/built-in.o(.text+0x82f5f): Section mismatch in reference from the function calculate_numa_remap_pages() to the function .init.text:reserve_early()
The function calculate_numa_remap_pages() references
the function __init reserve_early().
This is often because calculate_numa_remap_pages lacks a __init
annotation or the annotation of reserve_early is wrong.

Impact: fix panic on system 2g x4 sockets
Found one system with 4 sockets and every sockets has 2g can not boot
with numa32 because boot mem is crossing nodes.
So try to have numa version of setup_bootmem_allocator().

Impact: cleanup
This patch moves set_highmem_pages_init() to arch/x86/mm/highmem_32.c.
The declaration of the function is kept in asm/numa_32.h because
asm/highmem.h is included only if CONFIG_HIGHMEM is enabled so we
can't put the empty static inline function there.

Impact: fix crash during hibernation on 32-bit NUMA
The NUMA code on x86_32 creates special memory mapping that allows
each node's pgdat to be located in this node's memory. For this
purpose it allocates a memory area at the end of each node's memory
and maps this area so that it is accessible with virtual addresses
belonging to low memory. As a result, if there is high memory,
these NUMA-allocated areas are physically located in high memory,
although they are mapped to low memory addresses.
Our hibernation code does not take that into account and for this
reason hibernation fails on all x86_32 systems with CONFIG_NUMA=y and
with high memory present. Fix this by adding a special mapping for
the NUMA-allocated memory areas to the temporary page tables created
during the last phase of resume.
