[Qemu-devel] [RFC PATCH v0 2/9] cpu: Store CPU typename in MachineState

[Bharata B Rao <bharata@linux.vnet.ibm.com>]

Storing CPU typename in MachineState lets us to create CPU threads
for all architectures in uniform manner from arch-neutral code.

TODO: Touching only i386 and spapr targets for now
