Tejun Heo 8f05a6a65d percpu: make 4k first chunk allocator map memory ... At first, percpu first chunk was always setup page-by-page by the generic code. To add other allocators, different parts of the generic initialization was made optional. Now we have three allocators - embed, remap and 4k. embed and remap fully handle allocation and mapping of the first chunk while 4k still depends on generic code for those. This makes the generic alloc/map paths specifci to 4k and makes the code unnecessary complicated with optional generic behaviors. This patch makes the 4k allocator to allocate and map memory directly instead of depending on the generic code. The only outside visible change is that now dynamic area in the first chunk is allocated up-front instead of on-demand. This doesn't make any meaningful difference as the area is minimal (usually less than a page, just enough to fill the alignment) on 4k allocator. Plus, dynamic area in the first chunk usually gets fully used anyway. This will allow simplification of pcpu_setpu_first_chunk() and removal of chunk->page array. [ Impact: no outside visible change other than up-front allocation of dyn area ] Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Ingo Molnar <mingo@elte.hu>		2009-07-04 08:10:59 +09:00
