mm: fix prototype warning from kernel test robot
Patch series "mm: clean up names and parameters of memmap_init_xxxx functions", v5. This patchset corrects inappropriate function names of memmap_init_xxx, and simplify parameters of functions in the code flow. And also fix a prototype warning reported by lkp. This patch (of 5); Kernel test robot calling make with 'W=1' is triggering warning like below for memmap_init_zone() function. mm/page_alloc.c:6259:23: warning: no previous prototype for 'memmap_init_zone' [-Wmissing-prototypes] 6259 | void __meminit __weak memmap_init_zone(unsigned long size, int nid, | ^~~~~~~~~~~~~~~~ Fix it by adding the function declaration in include/linux/mm.h. Since memmap_init_zone() has a generic version with '__weak', the declaratoin in ia64 header file can be simply removed.
