As discussed in [1] add a prototype for __fortify_panic() to fix the
'make W=1 C=1' warning:
arch/x86/boot/compressed/misc.c:535:6: warning: symbol '__fortify_panic' was not declared. Should it be static?
Actually doesn't it make sense to have this defined under ../string.h ?
Actually given that we don't have any string fortification under the
boot/ why have the fortify _* functions at all ?
