Modified files:
sys/ia64/ia64 locore.S syscall.S
Log:
Slightly move labels around to make sure we call ast() on our way out
after a fork(2) in fork_trampoline(). By moving the epc_syscall_return
label immediately before the call to do_ast() in epc_syscall(), we not
only achieve that but also handle the detour through exception_return
when the frame corresponds to an asynchronous kernel entry. Hence, we
simplified fork_trampoline() as a side-effect.
