From: Nicola Vetrini <nicola.vetr...@bugseng.com> Function `reboot_machine' does not return, but lacks the `noreturn' attribute.
Functions that never return should be declared with a `noreturn' attribute. The lack of `noreturn' causes a violation of MISRA C Rule 17.11 (not currently accepted in Xen), and also Rule 2.1: "A project shall not contain unreachable code". Depending on the compiler used and the compiler optimization used, the lack of `noreturn' might lead to the presence of unreachable code. No functional change.
