Modified files:
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).
