3  * memory, for example, memory that is not managed by the regular
5  * memory, uncached memory etc.
14  * The lockless operation only works if there is enough memory
15  * available.  If new memory is added to the pool a lock has to be
17  * that sufficient memory is preallocated.
139  * gen_pool_create - create a new special memory pool
143  * Create a new special memory pool that can be used to manage special purpose
144  * memory not managed by the regular kmalloc/kfree interface.
161  * gen_pool_add_virt - add a new chunk of special memory to the pool
162  * @pool: pool to add new memory chunk to
163  * @virt: virtual starting address of memory chunk to add to pool
164  * @phys: physical starting address of memory chunk to add to pool
165  * @size: size in bytes of the memory chunk to add to pool
169  * Add a new chunk of special memory to the specified pool.
199  * gen_pool_virt_to_phys - return the physical address of memory
201  * @addr: starting address of memory
224  * gen_pool_destroy - destroy a special memory pool
227  * Destroy the specified special memory pool. Verifies that there are no
253  * gen_pool_alloc - allocate special memory from the pool
306  * gen_pool_free - free allocated special memory back to the pool
308  * @addr: starting address of memory to free back to pool
309  * @size: size in bytes of memory to free
311  * Free previously allocated special memory back to the specified
345  * gen_pool_for_each_chunk - call func for every chunk of generic memory pool
346  * @pool:	the generic memory pool
350  * Call @func for every chunk of generic memory pool.  The @func is
386  * gen_pool_size - get size in bytes of memory managed by the pool
389  * Return size in bytes of memory managed by the pool.
