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 ‘ident_pmd_init’: arch/x86/mm/ident_map.c:18:29: warning: suggest parentheses around arithmetic in operand of ‘|’ [-Wparentheses] set_pmd(pmd, __pmd(vaddr - off | info->pmd_flag));
Do you want to resend your version for integration?
