Tejun Heo	cae3aeb83f	percpu: clean up size usage ... Andrew was concerned about the unit of variables named or have suffix size. Every usage in percpu allocator is in bytes but make it super clear by adding comments. While at it, make pcpu_depopulate_chunk() take int @off and @size like everyone else.

Tejun Heo	fbf59bc9d7	percpu: implement new dynamic percpu allocator ... Impact: new scalable dynamic percpu allocator which allows dynamic percpu areas to be accessed the same way as static ones Implement scalable dynamic percpu allocator which can be used for both static and dynamic percpu areas. This will allow static and dynamic areas to share faster direct access methods. This feature is optional and enabled only when CONFIG_HAVE_DYNAMIC_PER_CPU_AREA is defined by arch. Please read comment on top of mm/percpu.c for details. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org>	2009-02-20 16:29:08 +09:00
