The kernel panics early in boot on a x86_64 server if the eXecute Disable (XD) bit is set to disabled in the uEFI firmware. The following patches fix the panic and also fix an error in kernel_map_pages_in_pgd() which would make the EFI runtime service unavailable when the XD bit is set to disabled.
