Dear Akemi,
I'm really ashamed, in
"https://wiki.centos.org/HowTos/I_need_the_Kernel_Source"; I've missed
the last 5 lines following the CentOS5 section. All is now clear for me
on the process to follow to build a new kernel from source rpm and the
CONFIG_NUMA_EMU option is active.
I've set it with make menuconfig to avoid some additional mistakes in
the config file.
However, with this CONFIG_NUMA_EMU option , the compiler returns an
error and compilation fails.
arch/x86/mm/srat_64.c: In function 'acpi_fake_nodes':
arch/x86/mm/srat_64.c:469: error: implicit declaration of function

Without CONFIG_NUMA_EMU option, compilation is successfull.
It is the CentOSplus kernel from
kernel-2.6.32-573.el6.centos.plus.src.rpm as yous suggested.
Redhat make very big changes to the base kernel source to create their
kernel - meaning that code they don't use (i.e. code included with
CONFIG options they don't support) may no longer build - as is probably
the case here
You may want to compare the 2.6.32-573 source with the generic 2.6.32
kernel source where your compile fails above to see if you can find a
workaround
A useful starting point could be:
http://lxr.free-electrons.com/ident?v=2.6.32;i=__acpi_map_pxm_to_node
However, there is no guarantee that even if you get it to compile that
it will work as expected ...
