4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Masami Hiramatsu <[email protected]> commit 5b4236e17cc1bd9fa14b2b0c7a4ae632d41f2e20 upstream. Since read_initrd() invokes alloc_bootmem() for allocating memory to load initrd image, it must be called after init_bootmem. This makes read_initrd() called directly from setup_arch() after init_bootmem() and mem_total_pages().
