Tejun Heo 099a19d91c percpu: allow limited allocation before slab is online ... This patch updates percpu allocator such that it can serve limited amount of allocation before slab comes online. This is primarily to allow slab to depend on working percpu allocator. Two parameters, PERCPU_DYNAMIC_EARLY_SIZE and SLOTS, determine how much memory space and allocation map slots are reserved. If this reserved area is exhausted, WARN_ON_ONCE() will trigger and allocation will fail till slab comes online. The following changes are made to implement early alloc. * pcpu_mem_alloc() now checks slab_is_available() * Chunks are allocated using pcpu_mem_alloc() * Init paths make sure ai->dyn_size is at least as large as PERCPU_DYNAMIC_EARLY_SIZE. * Initial alloc maps are allocated in __initdata and copied to kmalloc'd areas once slab is online.
