Tejun Heo bcb2107fdb sparc64: use embedding percpu first chunk allocator
sparc64 currently allocates a large page for each cpu and partially
remap them into vmalloc area much like what lpage first chunk
allocator did.  As a 4M page is used for each cpu, this results in
very large unit size and also adds TLB pressure due to the double
mapping of pages in the first chunk.

This patch converts sparc64 to use the embedding percpu first chunk
allocator which now knows how to handle NUMA configurations.  This
simplifies the code a lot, doesn't incur any extra TLB pressure and
results in better utilization of address space.
