I think "efi_use_11_map = true" should moved to before "#endif",
otherwise kernel will build fail on i586 architecture.

I got build error:
arch/x86/platform/efi/efi.c:1074: error: ‘efi_use_11_map’ undeclared (first use in this function)
arch/x86/platform/efi/efi.c:1074: error: (Each undeclared identifier is reported only once
arch/x86/platform/efi/efi.c:1074: error: for each function it appears in.)


Thanks a lot!
