I tested it and it worked well. I just got this warning on build:

In file included from arch/x86/mm/init_64.c:60:0:
arch/x86/mm/ident_map.c: In function âident_pmd_initâ:
arch/x86/mm/ident_map.c:18:29: warning: suggest parentheses around
arithmetic in operand of â|â [-Wparentheses]
    set_pmd(pmd, __pmd(vaddr - off | info->pmd_flag));

Do you want to resend your version for integration?
