If future changes will mistakenly make 32-bit x86 call native_read_cr8(), you will get no warning. (Hmmm. Maybe as will complain, I'm not sure). If it explicitly ifdefed out for 32 bits, it's easier to detect misuse. -- vda _______________________________________________ Virtualization mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/virtualization
