339  __set_bit - Set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* Unlike set_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation* succeeds.

名称描述
reserve_bootmem_regionInitialised pages do not have PageReserved set. This function is* called for each range allocated by the bootmem allocator and* marks the pages PageReserved. The remaining valid pages are later* sent to the buddy page allocator.
memmap_init_zoneInitially all pages are reserved - free ones are freed* up by memblock_free_all() once the early boot process is* done. Non-atomic initialization, single-pass.
