The arch_resume_nosmt() has a __weak definition, plus an x86 specific override, but no prototype that ensures the two have the same arguments. This causes a W=1 warning:
arch/x86/power/hibernate.c:189:5: error: no previous prototype for 'arch_resume_nosmt' [-Werror=missing-prototypes]
Add the prototype in linux/suspend.h, which is included in both places.
