percpu: reduce PCPU_MIN_UNIT_SIZE to 32k
In preparation of enabling percpu allocator for UP, reduce PCPU_MIN_UNIT_SIZE to 32k. On UP, the first chunk doesn't have to include static percpu variables and chunk size can be smaller which is important as UP percpu allocator will use contiguous kernel memory to populate chunks. PCPU_MIN_UNIT_SIZE also determines the maximum supported allocation size but 32k should still be enough. Signed-off-by: Tejun Heo <tj@kernel.org> Reviewed-by: Christoph Lameter <cl@linux.com>
