There are 4 wariants of initmem_init(), for 32 and 64 bits and for
CONFIG_NUMA enabled and disabled.
After commit bbeb69ce30 ("x86/mm: Remove CONFIG_HIGHMEM64G support")
NUMA is not supported on 32 bit kernels anymore, and
arch/x86/mm/numa_32.c can be just deleted and setup_bootmem_allocator()
with completely misleading name can be folded into initmem_init().
For 64 bits the NUMA variant calls x86_numa_init() and !NUMA variant
sets all memory to node 0. The later can be split out into inline helper
called x86_numa_init() and then both initmem_init() functions become the
same.
Split out memblock_set_node() from initmem_init() for !NUMA on 64 bit
into x86_numa_init() helper and remove arch/x86/mm/numa_*.c that only
contained initmem_init() variants for NUMA configs.
