Subject: [PATCH UPDATED 06/26] x86, NUMA: Move *_numa_init() invocations
into initmem_init()
There's no reason for these to live in setup_arch(). Move them inside
initmem_init().
* x86-32 initmem_init() weren't updated breaking 32bit builds. Fixed.

Updated to convert 32bit initmem_init() too. Both parameters weren't
being used in 32bit versions. git tree updated accordingly.
Thanks.
