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. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: David S.
