In function ‘bitmap_zero’,
    inlined from ‘cpumask_clear’ at ./include/linux/cpumask.h:378:2,
    inlined from ‘mm_init_cpumask’ at ./include/linux/mm_types.h:504:2,
    inlined from ‘efi_alloc_page_tables’ at 
arch/x86/platform/efi/efi_64.c:235:2:
./include/linux/bitmap.h:208:3: warning: ‘memset’ writing 64 bytes into a
