Subject: [PATCH -tip] x86: apic/nmi.c prev_nmi_count should be unsigned

Impact: fix sparse warning:
  arch/x86/kernel/apic/nmi.c:158:27: warning: incorrect type in argument 2 (different signedness)
  arch/x86/kernel/apic/nmi.c:158:27:    expected int *prev_nmi_count
  arch/x86/kernel/apic/nmi.c:158:27:    got unsigned int *[assigned] prev_nmi_count

prev_nmi_count is a non-negative count so it should be unsigned
