also will get error
arch/x86/mm/init_64.c: In function ‘ident_pud_init’:
arch/x86/mm/init_64.c:88:22: error: ‘struct mapping_info’ has no
member named ‘alloc_pages’

arch/x86/mm/init_64.c:121:22: error: ‘struct mapping_info’ has no
member named ‘alloc_pages’
because include/linux/gfp.h has
#define alloc_page(gfp_mask) alloc_pages(gfp_mask, 0)
so will stay with alloc.
