Replace fast_memset() by access_memset(), that first tries to probe
access to all affected pages (maximum is two). We'll use the same

correctly after a postcopy recovery so the recovered migration stream
will still eat the whole net bandwidth. Fix that up.

This is an effort to re-arrange few data structure for better
readability. Add X86CPUTopoInfo which will have all the topology
informations required to build the cpu topology. There is no
functional changes.

These functions add support for building new epyc mode topology
given smp details like numa nodes, cores, threads and sockets.
Subsequent patches will use these functions to build the topology.
The topology details are available in Processor Programming Reference (PPR)
for AMD Family 17h Model
Store the smp Sockets in CpuTopology. Socket information
is required to build the cpu topology in new epyc mode.
