Subject[PATCH] mm/memblock: add missing include <linux/bootmem.h> and #ifdef
Commit 26f09e9b3a06 ("mm/memblock: add memblock memory allocation apis")
introduced two new function definitions:


Commit ea1f5f3712af ("mm: define memblock_virt_alloc_try_nid_raw")
introduced the following function definition:


This commit adds an include of header file <linux/bootmem.h> to provide
the missing function prototypes. Silence the following gcc warning

mm/memblock.c:1334:15: warning: no previous prototype for `memblock_virt_alloc_try_nid_raw' [-Wmissing-prototypes]
mm/memblock.c:1371:15: warning: no previous prototype for `memblock_virt_alloc_try_nid_nopanic' [-Wmissing-prototypes]
mm/memblock.c:1407:15: warning: no previous prototype for `memblock_virt_alloc_try_nid' [-Wmissing-prototypes]

As seen in commit 6cc22dc08a24 ("revert "mm/memblock: add missing include
<linux/bootmem.h>"") #ifdef blockers were missing which lead to compilation
failure on mips/ia64 where CONFIG_NO_BOOTMEM=n.
