This patch will fix a boot memory reservation bug that trashes memory on
the ES7000 when loading the kdump crash kernel.
The code in arch/x86_64/kernel/setup.c to reserve boot memory for the
crash kernel uses the non-numa aware "reserve_bootmem" function instead
of the NUMA aware "reserve_bootmem_generic". I checked to make sure
that no other function was using "reserve_bootmem" and found none,
except the ones that had NUMA ifdef'ed out.
I have tested this patch only on an ES7000 with NUMA on and off (numa=off)
in a single (non-NUMA) and multi-cell (NUMA) configurations.
