    x86/boot: Declare error() as noreturn · 60854a12
    Kees Cook authored
    The compressed boot function error() is used to halt execution, but it
    wasn't marked with "noreturn". This fixes that in preparation for
    supporting kernel FORTIFY_SOURCE, which uses the noreturn annotation
    on panic, and calls error(). GCC would warn about a noreturn function
    calling a non-noreturn function:
      arch/x86/boot/compressed/misc.c: In function ‘fortify_panic’:
      arch/x86/boot/compressed/misc.c:416:1: warning: ‘noreturn’ function does return
