    sys/amd64/amd64      trap.c 
  Log:
  Fix restarted syscalls.  When we rewind %rip, we also need to restore
  all the argument registers etc since we have almost certainly have trashed
  them by now.  Take particular car of %r10 since it held the original value
  of %rcx (which we saved in tf_rcx on entry and doreti doesn't know this).
