Up until now the sparc64 kernel didn't use sparsemem thus some newer machines
(notably UltraSPARC-IIIi based SMP) didn't use all of the available memory
since each CPU has it's own memory controller and there were holes in the
memory layout.
The following patch enables sparsemem for sparc64.

sparsemem for sparc64 2.6.16+

This was merged into 2.6.16-git2, likely going mainstream for 2.6.17.
