Bug 753860

1.reproduce with kvm-243

steps to reproduce 

1.1) review kvm-243 source code(kvm-userspace-rhel5/kernel/external-module-compat.c)

 > ts.tv_sec = div_long_long_rem_signed(nsec, NSEC_PER_SEC, &ts.tv_nsec); 
 > if (unlikely(nsec < 0))
 > kvm_set_normalized_timespec(&ts, ts.tv_sec, ts.tv_nsec);

1.2) compile kvm-243
   /root/kvm-userspace-rhel5/kernel/x86/../external-module-compat.c:284: warning: ‘kvm_set_normalized_timespec’ defined but not used

actual result:
  broke the compilation of the KVM userspac

2. verify with kvm-246
  
 steps to verify:
2.1)review kvm-246 source code
  <     s32 rem;
  <     ts.tv_sec = div_s64_rem(nsec, NSEC_PER_SEC, &rem);
  <     if (unlikely(rem < 0)) {
  <           ts.tv_sec--;
  <           rem += NSEC_PER_SEC;
  <      }
  <     ts.tv_nsec = rem;

2.2)compile kvm-246
 
actual result:
   compile successfully,and make install successfully too.

base on above testing result, I think this bug is fixed.
