The low-level guts to support MTP (Multi-Threaded Processing) on the
Fujitsu SPARC64-VI and SPARC64-VII CPUs. Since the two threads on each core
share the TLBs of the core we cannot enter different mappings for the same
virtual address. Instead we use a scratch register to store the per-cpu
pointer. This is very similar to what we do on sun4v.
For now we still only attach the first thread of each SPARC64-VI/VII core
since we currently don't handle the VMT (Vertical Multi-Threading) of the
SPARC64-VI very well.
